EliotBlennerhassett: add example volume control names

[[Category:Architecture-x86]]

Driver for cards from [[Matrix:Vendor-AudioScience]]
{| align="right"
| __TOC__
|}
==Card Specific Information==
=== Additional Installation notes===

The asihpi driver was merged with mainline kernel at version 2.6.35. However, to keep up with latest developments you may need to build from source.

In addition to the alsa-driver source package, the matching alsa-firmware package must be downloaded, and run "make install" in the asihpi subdirectory.

If you have installed the hpklinux driver available from [http://audioscience.com/internet/download/linux_drivers.htm AudioScience website], you will end up with two different drivers that can claim the cards.
To avoid unexpected behaviour, either remove one of the drivers or blacklist one or both E.g add "blacklist asihpi" to /etc/modprobe.d/blacklist. If both drivers are blacklisted, it is still possible to load either of them manually using modprobe.

Also you need to take care that incompatible firmware is not installed. In this case, it is recommended to rebuild the alsa driver using source from the hpklinux package (see that package for instructions).

=== Card indices ===
AudioScience cards have a hardware jumper to specify the card index. This ensures that cards keep the same index even if they are moved between slots, or other cards are added.

The driver will try to make ALSA card indices match the card jumper settings. This may fail if another card (onboard sound) is present and has already claimed a desired index. The cards will still work, but have unexpected indices.

By default the card name shown by ALSA will be the card model eg "ASI6644"

=== PCM streams ===
AudioScience cards support multiple streams (PCMs). These are exposed as ALSA substreams of device 0. I.e. hw:0,0,0 hw:0,0,1 etc.

The reason the driver doesn't map streams to ALSA devices is that there is a limit of four devices per card, and some cards have up to 16 streams.

Streams do not correspond to physical inputs and outputs, see Mixer section for more on this.

=== Mixer ===
==== control names ====
Controls use ALSA naming conventions that differ from AudioScience HPI names.

{| border="1"
!ALSA
! HPI
|-
| PCM
| Stream
|-
| Capture
| In
|-
| Playback
| Out
|-
| Clock
| SampleClock
|-
| Digital
| AES/EBU
|-
| Mode
| ChannelMode
|-
| Route
| Multiplexer
|-
| Switch
| Mute
|-
| Volume, Level, Meter
| same
|}

For example HPI "LineOut 0 Level" becomes ALSA "Line 0 Playback Level"

The general format for an ALSA control name is "SOURCE SINK DIRECTION TYPE". Some examples 
"PCM 0 Playback Volume" = master volume of player 0 
"PCM 0 Line 0 Playback Volume" = matrix volume between player 0 and output 0 
"Line 0 Line 0 Monitor Playback Volume" = feedthrough volume from input 0 to output 0 
"PCM 0 Capture Route" = select one source for recorder 0 (more common) 
"Line 0 PCM 0 Capture Volume" = matrix volume between input 0 and recorder 0 (less common alternative to capture route)

==== setting card master samplerate ====
Most cards will have a Sample Rate control. This sets the master samplerate for the card. The default rate will be 44100 or 48000. Setting this to the same rate as your source material means that the card will not have to do sample rate conversion.

Read the control <tt>amixer -c1 cget name='Clock0 LocalRate'</tt>

Set a new rate <tt>amixer -c1 cset name='Clock0 LocalRate' 48000</tt>

==== Level controls ====
Note that input level controls do not set input gain directly. The setting of an input level control is the full scale input signal level in dBu. So increasing input level control DECREASES the input gain.

Likewise, the setting of output level controls is the fullscale output level in dBu

=== Linked streams ===

Most AudioScience cards support multiple independent stereo play and record streams with different formats and samplerates (not ASI5xxx)

ALSA allows streams to be grouped together into a virtual stream with more channels using the ''multi'' plugin, maybe also requiring ''ttable'' plugin to allow memory mapped operation of the virtual stream.

To support stream grouping with the multi plugin, the card must support mmap. This will be reported in "dmesg" when the driver loads as ''Supports mmap:1''

Cards which support hardware linking of streams for sample-accurate start and stop report ''grouping:1''

Example definitions for .asoundrc
<pre>
# create a virtual four-channel device with two sound devices:
# This is in fact two interleaved stereo streams in
# This creates a 4 channel interleaved pcm stream based on
# the multi device. JACK will work with this one.

==Template Matrix:Soundcard==

This is the generic ALSA module template which is intended to give an overview for '''all''' sound modules.

If you want to add specific hardware information or information for a specific module, please '''DO NOT modify''' this template. Add extra information above and/or bellow to the specific Matrix:Module-* page instead. Please read the [[Matrix:Description|Universal Soundcard Description]] for more details.

</noinclude>==Introduction for {{{name|unknown}}} soundcard==

There are two ways of getting Linux drivers to work, you can either compile them into the kernel or build them separately as modules. Read the [http://www.tldp.org/ Kernel-HOWTO] for details of how to compile a kernel.

'''You must turn on the sound support soundcore module.''' This is in the kernel. Look in the sound drivers directory and it should be the first option. Most people enable the module setting. That way you can load and unload the module manually if you have multiple soundcards/devices or if you intend to debug or use cutting edge software which may cause your drivers to halt sometimes. Of course it also means you have more control of your system.

Most modern distros come with <tt>soundcore</tt> compiled as a module. You can check this in numerous ways. The easiest way is to type:

modinfo soundcore

If this command returns that you have this module, then you don't need to recompile your kernel.

==Quick installation==

This explains how to build from source tarballs. See [[GIT_Server]] for instructions on getting and using the latest source from git repositories.

Type the following commands in the shell of your choice.

Make a directory to store the alsa source code in:

cd /usr/src
mkdir alsa
cd alsa
cp /downloads/alsa-* .

Now unzip and install the <tt>alsa-driver</tt> package:

bunzip2 alsa-driver-xxx
tar -xf alsa-driver-xxx
cd alsa-driver-xxx
./configure --with-cards={{{module|unknown}}} --with-sequencer=yes ; make ; make install

Now unzip and install the <tt>alsa-lib</tt> package:

cd ..
bunzip2 alsa-lib-xxx
tar -xf alsa-lib-xxx
cd alsa-lib-xxx
./configure ; make ; make install

Now unzip and install the <tt>alsa-utils</tt> package:

cd ..
bunzip2 alsa-utils-xxx
tar -xf alsa-utils-xxx
cd alsa-utils-xxx
./configure ; make ; make install

Now insert the modules into the kernel:

modprobe snd-{{{module|unknown}}} ; modprobe snd-pcm-oss ; modprobe snd-mixer-oss ; modprobe snd-seq-oss

Now adjust your soundcard's volume levels. All mixer channels are muted by default. You must use a native mixer program to unmute appropriate channels, for example <tt>alsamixer</tt> from the <tt>alsa-utils</tt> package. Note that some usb-audio devices do not have internal mixer controls. Run:

alsamixer

You can also look at the utils/alsasound file. This script is designed for the ''RedHat Linux'' distribution, but it can also be used with other distributions which use System V style rc init scripts. This will allow you to load your modules at boot time. If you don't want to do this you can of course compile them into the kernel instead and save yourself the hassle of coming to terms with the rc init scripts.

===Setting up modprobe and kmod support===

Before you send a mail complaining that "I don't have <tt>/etc/modules.conf</tt>, where do I find it ……" ‒ the <tt>/etc/conf.modules</tt> has been deprecated with a few distro's, but in your case it may still be <tt>/etc/conf.modules</tt>. Basically they are both the same, but recent version of <tt>modutils</tt> use <tt>/etc/modules.conf</tt> instead. Nothing to worry about as such, optionally please update to the latest version of <tt>modutils</tt>. This should solve your problem.

Here's the example for this card. Copy and paste this to the bottom of your <tt>/etc/modules.conf</tt> file.

{{Note|'''Debian GNU/Linux users''' need to save this information into a file in the <tt>/etc/modutils/</tt> directory (eg. <tt>/etc/modutils/alsa</tt>) and run <tt>update-modules</tt>. 

Note also that the kernel module '''soundcore''' has been renamed in Debian kernels >2.6.23 into '''snd'''. A workaround is to put a symlink at /lib/modules/x.x.xx/kernel/sound/soundcore.ko pointing to '''snd.ko'''}}

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-{{{module|unknown}}}
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

To copy and paste the above to your <tt>/etc/modules.conf</tt> file follow these [http://www.alsa-project.org/alsa-doc/doc-php/file-edit.php instructions].

==modules.conf==

This is a short explanation of what happens in the <tt>/etc/modules.conf</tt> file.

===Native devices===

After the main multiplexer is loaded, its code automatically requests the top level sound card module. String <tt>snd-card-''%i''</tt> is requested for native devices where ''%i'' is the sound card number, counted from zero (the first sound card) to seven (the eighth sound card). String <tt>sound-slot-''%i''</tt> is requested for native devices where ''%i'' is slot number for the corresponding ALSA owner (which is basically the sound card number). The options line allows you to set various configuration options before the module is loaded. String <tt>id</tt> (or <tt>snd_id</tt>) lets you set the name of the card which is then returned in the <tt>/proc/asound/cards</tt> file, i.e. to user space applications. Other options may be available depending on the specific card. Options for these cards are found in the <tt>INSTALL</tt> file or above.

username@hostname# pico /etc/modules.conf

# ALSA portion
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-cmipci
options snd-cmipci id="first" mpu_port=0x330

# OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1

{{Note|
''For drivers older than 0.9.0rc5 use:''

<nowiki>options snd-cmipci snd_id="first" snd_mpu_port=0x330</nowiki>
|NB}}

{{Note|The "<tt>snd_</tt>" prefix has been removed from the module options to fit with the kernel standard.|NB}}

===Autoloading OSS/free emulation===

At this point we are finished with the configuration for ALSA native devices, but you may also need autoloading for the OSS/Free emulation modules, an ALSA add-on. At this time only one module does not depend on any others, thus must be loaded separately: <tt>snd-pcm1-oss</tt>. String <tt>sound-service-''%i''-''%i''</tt> is required for OSS/Free service where the first ''%i'' is the slot number/sound card number and the second ''%i'' is the service number.

username@hostname# pico /etc/modules.conf

# OSS/Free portion - card #1
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

# OSS/Free portion - card #2 (cmipci)
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss

The alias for <tt>snd-seq-oss</tt> is not necessary on the second device, because there is only one <tt>/dev/sequencer</tt> regardless how many devices you have.

===The .asoundrc file===

[[Asoundrc|This file]] allows you to have more advanced control over your card/device. For most setups the default, system-wide configuration is sufficient. You may change this file only for special setup. The <tt>.asoundrc</tt> file consists of definitions for the various sound devices available in your system. It also provides access to the pcm plugins in <tt>alsa-lib</tt>. These allow you to do tricky things like combine your cards into one or access multiple I/O streams on your multi-channel card.

Below is the most basic definition (only example - not required to define at all).

Make a file called <tt>.asoundrc</tt> in your home and/or root directory:

vi ~/.asoundrc

Copy and paste the following into the file, then save it:

pcm.{{{module|unkown}}} {
type hw
card 0
}

ctl.{{{module|uknown}}} {
type hw
card 0
}

==== setting card master samplerate ====
Most cards will have a Sample Rate control. This sets the master samplerate for the card. The default rate will be 44100 or 48000. Setting this to the same rate as your source material means that the card will not have to do sample rate conversion.

EliotBlennerhassett: update ALSA to HPI name translation

[[Category:Architecture-x86]]

Driver for cards from [[Matrix:Vendor-AudioScience]]
{| align="right"
| __TOC__
|}
==Card Specific Information==
=== Additional Installation notes===

The asihpi driver was merged with mainline kernel at version 2.6.35. However, to keep up with latest developments you may need to build from source.

In addition to the alsa-driver source package, the matching alsa-firmware package must be downloaded, and run "make install" in the asihpi subdirectory.

If you have installed the hpklinux driver available from [http://audioscience.com/internet/download/linux_drivers.htm AudioScience website], you will end up with two different drivers that can claim the cards.
To avoid unexpected behaviour, either remove one of the drivers or blacklist one or both E.g add "blacklist asihpi" to /etc/modprobe.d/blacklist. If both drivers are blacklisted, it is still possible to load either of them manually using modprobe.

Also you need to take care that incompatible firmware is not installed. In this case, it is recommended to rebuild the alsa driver using source from the hpklinux package (see that package for instructions).

=== Card indices ===
AudioScience cards have a hardware jumper to specify the card index. This ensures that cards keep the same index even if they are moved between slots, or other cards are added.

The driver will try to make ALSA card indices match the card jumper settings. This may fail if another card (onboard sound) is present and has already claimed a desired index. The cards will still work, but have unexpected indices.

By default the card name shown by ALSA will be the card model eg "ASI6644"

=== PCM streams ===
AudioScience cards support multiple streams (PCMs). These are exposed as ALSA substreams of device 0. I.e. hw:0,0,0 hw:0,0,1 etc.

The reason the driver doesn't map streams to ALSA devices is that there is a limit of four devices per card, and some cards have up to 16 streams.

Streams do not correspond to physical inputs and outputs, see Mixer section for more on this.

=== Mixer ===
==== control names ====
Controls use ALSA naming conventions that differ from AudioScience HPI names. The following table summarises the translation

{| border="1"
!ALSA
! HPI
|-
| PCM
| Stream
|-
| Capture
| In
|-
| Playback
| Out
|-
| Clock
| SampleClock
|-
| Digital
| AES/EBU
|-
| Mode
| ChannelMode
|-
| Route
| Multiplexer
|-
| Switch
| Mute
|}

HPI "LineOut 0 Level" becomes ALSA "Line 0 Playback Level"

==== setting card master samplerate ====
Most cards will have a Sample Rate control. This sets the master samplerate for the card. The default rate will be 44100 or 48000. Setting this to the same rate as your source material means that the card will not have to do sample rate conversion.

Read the control <tt>amixer -c1 cget name='Clock0 LocalRate'</tt>

Set a new rate <tt>amixer -c1 cset name='Clock0 LocalRate' 48000</tt>

==== Level controls ====
Note that input level controls do not set input gain directly. The setting of an input level control is the full scale input signal level in dBu. So increasing input level control DECREASES the input gain.

Likewise, the setting of output level controls is the fullscale output level in dBu

=== Linked streams ===

Most AudioScience cards support multiple independent stereo play and record streams with different formats and samplerates (not ASI5xxx)

ALSA allows streams to be grouped together into a virtual stream with more channels using the ''multi'' plugin, maybe also requiring ''ttable'' plugin to allow memory mapped operation of the virtual stream.

To support stream grouping with the multi plugin, the card must support mmap. This will be reported in "dmesg" when the driver loads as ''Supports mmap:1''

Cards which support hardware linking of streams for sample-accurate start and stop report ''grouping:1''

Example definitions for .asoundrc

# create a virtual four-channel device with two sound devices:
# This is in fact two interleaved stereo streams in
# This creates a 4 channel interleaved pcm stream based on
# the multi device. JACK will work with this one.

Streams do not correspond to physical inputs and outputs, see Mixer section for more on this.

=== Mixer ===
==== control names ====
By default the controls have names that follow AudioScience naming conventions. These reflect ASI documentation and will be familiar to users of the card via HPI or windows drivers.

Main differences: OutStream == PCM Playback, InStream == PCM Capture, AesIn == Digital in

It is possible to build the driver with more ALSA-style names by editing asihpi.c and removing the definition ASI_STYLE_NAMES

As of about 20071101 the controls no longer use indices (all have index=0). The node indices have been assimilated into the control names. E.g. "Outstream to Lineout3", 4 has become Outstream3 to Lineout3.
All indices are now zero-based, corresponding to PCM substream numbering.

==== setting card master samplerate ====
Most cards will have a Sample Rate control. This sets the master samplerate for the card. The default rate will be 44100 or 48000. Setting this to the same rate as your source material means that the card will not have to do sample rate conversion.

==For developers - kernel drivers==

===Common rules===

: 1) be very very very carefull when you use '--force' for 'git push', you can broke whole repository
: 2) valid 'Signed-off-by:' line must be in the commit text

===Rules for alsa-kernel.git===

: 1) subject (first commit text line) must start with '[ALSA] ' or 'ALSA: '

===Syncing===

Note that 'master' branch in alsa-kernel.git is synced with alsa-kmirror.git 'master' branch automatically. So if you add a patch to alsa-kernel.git, it will be merged to alsa-kmirror.git (if no problem occurs) when you initiate 'git push' to the ALSA server. It's really required to see messages from the pre-receive script when something goes wrong. The script is trying to suggest what's going wrong and try to show you a problematic code (diff).

Pushing to 'alsa-kmirror.git' should be only done if:

: a) you fixing a sync problem
: b) you are modifying a file which is out of sync (scripts directory or so)

In all other cases, only alsa-kernel.git repository should be used.

The pre-receive script uses all four commit identifiers Author + AuthorDate + Commit + CommitDate to pair commits between alsa-kernel.git and alsa-kmirror.git. Use this information, if you like to add some commits manually to alsa-kmirror.git tree.

====Common problems====

; PRE-RECEIVE repositories does not match, please, fix it
: The alsa-kmirror.git#mastter and alsa-kernel.git#master sources does not match. You have to do manual changes in alsa-kmirror.git repository to sync trees. A diff between alsa-kmirror.git and alsa-kernel.git is printed to stderr, so you can analyze it and do appropriate steps.

; PRE-RECEIVE Patch failed - is it already merged?
: Appearently, you're trying to apply a patch which cannot be applied cleanly to alsa-kmirror.git#master. One reason might be that the patch is already applied, but the pre-receive script does not know about it. You may add commiter and commitdate to alsa-kmirror/scripts/git-ok-commits file to skip problematic commit (but only if you really verify, that this commit is already in the alsa-kmirror tree).

===Clone repositories===

git clone git@git.alsa-project.org:alsa-driver.git alsa-driver
git clone git@git.alsa-project.org:alsa-kernel.git alsa-kernel
git clone git@git.alsa-project.org:alsa-kmirror.git alsa-kmirror

To show all branches (includes remote ones):

git branch -a

To make a remote branch local:

git checkout -b for-linus origin/for-linus
git checkout -b linux-2.6 origin/linux-2.6

===Update and rebase using Linus's 2.6 kernel tree===

Add remote URL:

git remote add linux-2.6 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

Checkout linux-2.6 branch:

git checkout linux-2.6

Pull Linus's 2.6 changes:

git pull linux-2.6 master

Rebase our main ALSA development master branch with linux-2.6:

git rebase linux-2.6 master

===Push branch changes to ALSA GIT repository===

git push --tags origin master:refs/heads/master
git push --tags origin linux-2.6:refs/heads/linux-2.6
git push --tags origin for-linus:refs/heads/for-linus

Note: Especially after 'git rebase' the repository on server is not consistent with local repository (remote ref is not ancestor of the local ref for master branch), so you have to use --force parameter for 'git push' command. Note that this might be dangerous - we probably need to settle a locking mechanism to prevent inconsistent changes.

===Branches===

; master
: this branch is for main development (Andrew Morton will get patches for mm tree)

; for-linus
: this branch is for mainstream tree (for Linus Torvalds)

; linux-2.6
: this is official linux 2.6 mainstream tree

; stable-2.6.<number>
: patches for stable 2.6 kernels

; private-*
: all developers can create a private branch to test a particular set of patches, prefix for these branches is 'private-' (for example private-alsabug-1234, private-tiwai-vmaster etc.)

===Tags===

Private tags are not allowed. Only tags identifying ALSA version (alsa-kmirror.git and alsa-driver.git) or official linux kernel version (alsa-kernel.git) are allowed.

===Maintenance===

GIT server is maintaned by [[User:Perex]].

==Occasional Developers==
This section is for developers without write access to ALSA git. I.e. who will clone repos and send in patches

===clone the repository===
git clone git://git.alsa-project.org/alsa-driver.git alsa-driver
git clone git://git.alsa-project.org/alsa-kmirror.git alsa-kmirror

===configure git===
Set your email address correctly otherwise commits get spurious email address for Author and Commiter
git-config --add user.email me@domain.com

Make sure it knows how to send email (for patches)
git-config --add sendemail.smtpserver smtp.domain.com

===save current===
in case you want to roll back
git-branch save

===do your work===
edit, compile, test, sweat

If it didn't work out and you want to get back to the old tree
git-reset --hard save

===generate patches===
Want to get patch against latest, so rebase
git-rebase origin/master
git-diff remotes/origin/master

Then do this to generate the patchset
git-format-patch -s -n -p --subject-prefix="PATCH - my module" remotes/origin/master

===check the patches===
/lib/modules/`uname -r`/build/scripts/checkpatch.pl --no-tree *.patch

===sending the patches===

git-send-email --from=me --to=tiwai@suse.de --cc=alsa-devel@alsa-project.org
000*.patch

===get up to date===
For both alsa-kmirror and alsa-driver
git-pull

Sometimes you can just make and things will be fine. However, when there have been changes to the build system etc, its best to do a make clean; ./gitcompile to get the tree properly up to date.

Driver for cards from [[Matrix:Vendor-AudioScience]]
{| align="right"
| __TOC__
|}
==Card Specific Information==
=== Additional Installation notes===
The asihpi driver is not yet in the official kernel part of ALSA, so must be built from source.

In addition to the alsa-driver source package, the matching alsa-firmware package must be downloaded, and run "make install" in the asihpi subdirectory.

If you have installed the hpklinux driver available from [http://audioscience.com/internet/download/linux_drivers.htm AudioScience website], you will end up with two different drivers that can claim the cards.
To avoid unexpected behaviour, either remove one of the drivers or blacklist one or both E.g add "blacklist asihpi" to /etc/modprobe.d/blacklist. If both drivers are blacklisted, it is still possible to load either of them manually using modprobe.

Also you need to take care that incompatible firmware is not installed. In this case, it is recommended to rebuild the alsa driver using source from the hpklinux package (see that package for instructions).

=== Card indices ===
AudioScience cards have a hardware jumper to specify the card index. This ensures that cards keep the same index even if they are moved between slots, or other cards are added.

The driver will try to make ALSA card indices match the card jumper settings. This may fail if another card (onboard sound) is present and has already claimed a desired index. The cards will still work, but have unexpected indices.

By default the card name shown by ALSA will be the card model eg "ASI6644"

=== PCM streams ===
AudioScience cards support multiple streams (PCMs). These are exposed as ALSA substreams of device 0. I.e. hw:0,0,0 hw:0,0,1 etc.

The reason the driver doesn't map streams to ALSA devices is that there is a limit of four devices per card, and some cards have up to 16 streams.

Streams do not correspond to physical inputs and outputs, see Mixer section for more on this.

=== Mixer ===
==== control names ====
By default the controls have names that follow AudioScience naming conventions. These reflect ASI documentation and will be familiar to users of the card via HPI or windows drivers.

Main differences: OutStream == PCM Playback, InStream == PCM Capture, AesIn == Digital in

It is possible to build the driver with more ALSA-style names by editing asihpi.c and removing the definition ASI_STYLE_NAMES

As of about 20071101 the controls no longer use indices (all have index=0). The node indices have been assimilated into the control names. E.g. "Outstream to Lineout3", 4 has become Outstream3 to Lineout3.
All indices are now zero-based, corresponding to PCM substream numbering.

==== setting card master samplerate ====
Most cards will have a Sample Rate control. This sets the master samplerate for the card. The default rate will be 44100 or 48000. Setting this to the same rate as your source material means that the card will not have to do sample rate conversion.

Read the control <tt>amixer -c1 cget name='Clock0 LocalRate'</tt>

Set a new rate <tt>amixer -c1 cset name='Clock0 LocalRate' 48000</tt>

==== Level controls ====
Note that input level controls do not set input gain directly. The setting of an input level control is the full scale input signal level in dBu. So increasing input level control DECREASES the input gain.

Likewise, the setting of output level controls is the fullscale output level in dBu

=== Linked streams ===

Most AudioScience cards support multiple independent stereo play and record streams with different formats and samplerates (not ASI5xxx)

ALSA allows streams to be grouped together into a virtual stream with more channels using the ''multi'' plugin, maybe also requiring ''ttable'' plugin to allow memory mapped operation of the virtual stream.

To support stream grouping with the multi plugin, the card must support mmap. This will be reported in "dmesg" when the driver loads as ''Supports mmap:1''

Cards which support hardware linking of streams for sample-accurate start and stop report ''grouping:1''

It is possible to build the driver with more ALSA-style names by editing asihpi.c and removing the definition ASI_STYLE_NAMES

==== rationale for indexing ====
Controls with the same name have indices starting at '1'. This is because '''alsamixer''' displays controls with index=0 differently. Eg "OutStream" not "OutStream 0". In addition, the cables/breakout boxes supplied with the cards are numbered starting from 1.

However, this can lead to confusion where control 1 corresponds to alsa stream 0. :(

==== setting card master samplerate ====
Most cards will have a Sample Rate control. This sets the master samplerate for the card. The default rate will be 44100 or 48000. Setting this to the same rate as your source material means that the card will not have to do sample rate conversion.

Note that input level controls do not set input gain directly. The setting of an input level control is the full scale input signal level in dBu. So increasing input level control DECREASES the input gain.

Likewise, the setting of output level controls is the fullscale output level in dBu

=== Linked streams ===

Most AudioScience cards support multiple independent stereo play and record streams with different formats and samplerates (not ASI5xxx)

ALSA allows streams to be grouped together into a virtual stream with more channels using the ''multi'' plugin, maybe also requiring ''ttable'' plugin to allow memory mapped operation of the virtual stream.

To support stream grouping with the multi plugin, the card must support mmap. This will be reported in "dmesg" when the driver loads as ''Supports mmap:1''

Cards which support hardware linking of streams for sample-accurate start and stop report ''grouping:1''

<pre>
# create a virtual four-channel device with two sound devices:
# This is in fact two interleaved stereo streams in
# This creates a 4 channel interleaved pcm stream based on
# the multi device. JACK will work with this one.

EliotBlennerhassett: expand linked streams info, provide example asoundrc

Driver for cards from [[Matrix:Vendor-AudioScience]]
{| align="right"
| __TOC__
|}
==Card Specific Information==
=== Additional Installation notes===
The asihpi driver is not yet in the official kernel part of ALSA, so must be built from source.

In addition to the alsa-driver source package, the matching alsa-firmware package must be downloaded, and run "make install" in the asihpi subdirectory.

If you have installed the hpklinux driver available from [http://audioscience.com/internet/download/linux_drivers.htm|AudioScience website], you will end up with two different drivers that can claim the cards.
To avoid unexpected behaviour, either remove one of the drivers or blacklist one or both E.g add "blacklist asihpi" to /etc/modprobe.d/blacklist. If both drivers are blacklisted, it is still possible to load either of them manually using modprobe.

Also you need to take care that incompatible firmware is not installed. In this case, it is recommended to rebuild the alsa driver using source from the hpklinux package (see that package for instructions).

=== Card indices ===
AudioScience cards have a hardware jumper to specify the card index. This ensures that cards keep the same index even if they are moved between slots, or other cards are added.

The driver will try to make ALSA card indices match the card jumper settings. This may fail if another card (onboard sound) is present and has already claimed a desired index. The cards will still work, but have unexpected indices.

By default the card name shown by ALSA will be the card model eg "ASI6644"

=== PCM streams ===
AudioScience cards support multiple streams (PCMs). These are exposed as ALSA substreams of device 0. I.e. hw:0,0,0 hw:0,0,1 etc.

The reason the driver doesn't map streams to ALSA devices is that there is a limit of four devices per card, and some cards have up to 16 streams.

Streams do not correspond to physical inputs and outputs, see Mixer section for more on this.

=== Mixer ===
# mixer controls, rationale for indexing
# control names
# setting card master samplerate

=== Linked streams ===

Most AudioScience cards support multiple independent stereo play and record streams with different formats and samplerates (not ASI5xxx)

ALSA allows streams to be grouped together into a virtual stream with more channels using the ''multi'' plugin, maybe also requiring ''ttable'' plugin to allow memory mapped operation of the virtual stream.

To support stream grouping with the multi plugin, the card must support mmap. This will be reported in "dmesg" when the driver loads as ''Supports mmap:1''

Cards which support hardware linking of streams for sample-accurate start and stop report ''grouping:1''

Grrr. Including category pages doesn't show the list of pages in that category!

Including the pages just gives their fixed text:

EliotBlennerhassett: update links to asoundrc and install doc

User contributed notes and additions can be added to pages of the [[Matrix:Main|soundcard matrix]].
Feel free to make additions and contributions. This is the official reference for user docs.

See also [http://alsa.opensrc.org/ unofficial wiki]. Feel free to make additions and contributions.

The online alsa-docs (above) have info on using the [[asoundrc|.asoundrc]] file. You can find more in the [http://alsa.opensrc.org/index.php?page=.asoundrc Unofficial ALSA WIKI] and the [http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html#pcm_plugins alsa-lib documentation].

Take a look at the latest [http://hg-mirror.alsa-project.org/alsa-driver/file/9e029f63e883/INSTALL alsa-driver/INSTALL] file to read information about the newest drivers and their use. If you have questions ask on the [[Mailing-lists|mailing lists]].

Yes, from our main site - http://www.alsa-project.org .

Version is available in linux/include/sound/version.h

ALSA library has a copy of kernel header files and it is backwards
compatible with ALSA code 0.9 final (which is also in the 2.6 kernel
tree). In other words, you can use 1.0 packages without any problems.

> Is there some sane method to intergrate ALSA from CVS into whatever

ftp://ftp.alsa-project.org/pub/kernel-patches .

or (use BitKeeper):

bk pull http://linux-sound.bkbits.net/linux-sound

or

simply copy files from the ALSA's alsa-kernel CVS module to relevant
locations in the 2.6 kernel tree.

Asoundrc

2007-08-14T23:06:23Z

EliotBlennerhassett: migrate from old-www

==Why asoundrc?==

What is it good for, why do I want one?

Neither the .asoundrc nor the asound.conf files are required for ALSA to work properly. Most applications will work without them. They are used to allow extra functionality, such as routing and sample-rate conversion, through the alsa-lib layer.

==The .asoundrc file==

This file allows the you to have more advanced control over your card/device. The .asoundrc file consists of definitions of the various cards available in your system. It also gives you access to the pcm plugins in alsa-lib. These allow you to do tricky things like combine your cards into one or access multiple i/o's on your mulitchannel card.

==Where does asoundrc live?==

The asoundrc file is typically installed in a user's home directory

$HOME/.asoundrc

and is called from

/usr/share/alsa/alsa.conf

It is also possible to install a system wide configuration file as

/etc/asound.conf

When an alsa application starts both configuration files are read.

Below is the most basic definition.

==The default plugin==

Make a file called .asoundrc in your home and/or root directory.

vi /home/xxx/.asoundrc

copy and paste the following into the file then save it.

pcm.!default {
type hw
card 0
}

ctl.!default {
type hw
card 0
}

The keyword default is defined in the ALSA lib api and will always access hw:0,0 - the default device on the default soundcard. Specifying the !default name supercedes the one defined in the ALSA lib api.

Now you can test:

aplay -D default test.wav

==The naming of PCM devices==

A typical asoundrc starts with a 'PCM hw type'. This gives an ALSA application the ability to start a virtual soundcard (plugin, or slave) by a given name. Without this, the soundcard(s)/devices(s) must be accessed with names like hw:0,0 or default. For example:

aplay -D hw:0,0 test.wav

or with ecasound

ecasound -i test.wav -o alsa,hw:0,0

The numbers after hw: stand for the soundcard number and device number. This can get confusing as some sound "cards" are better represented by calling them sound "devices", for example USB sounddevices. However they are still "cards" in the sense that they have a specific driver controlling a specific piece of hardware. They also correspond to the index shown in

/proc/asound/cards

As with most arrays the first item usually starts at 0 not 1. This is true for the way pcm devices (physical i/o channels) are represented in ALSA. Starting at pcm0c (capture), pcm0p (playback).

We use subdevices mainly for hardware which can mix several streams together. It is impractical to have 32 devices with exactly the same capabilities. The subdevices can be opened without a specific address, so the first free subdevice is opened. Also, we temporarily use subdevices for hardware with alot of streams (I/O connectors) - for example MIDI. There are several limits given by used minor numbers (8 PCM devices per card, 8 MIDI devices per card etc.).

For example, to access the first device on the first soundcard/device, you would use

hw:0,0

to access the first device on the second soundcard/device, you would use

hw:1,0

to access the second device on the third soundcard/device, you would use

hw:2,1

The Control device

The control device for a card is the way that programs modify various "controls" on the card. For many cards this includes the mixer, some cards, for example the rme9652, have no mixer. However, they do still have a number of other controls and some programs like JACK need to be able to access them. Examples include the digital i/o sync indicators, sample clock source switch and so on.

==Aliases==

With the 'PCM hw type' you are able to define aliases for your devices. The syntax for this definition is:

pcm.NAME {
type hw # Kernel PCM
card INT/STR # Card name or number
[device] INT # Device number (default 0)
[subdevice] INT # Subdevice number, -1 first available (default -1)
mmap_emulation BOOL # enable mmap emulation for ro/wo devices
}

For example, this gives your first soundcard an alias:

pcm. {
type hw
card 0
device 0
}

Now you can access this card by the alias ''.

aplay -D test.wav

==Plugins==

To see a full list of plugins visit the alsa-lib documentation which is generated daily from cvs.

Q: What are plugins?

A: In ALSA, PCM plugins extend functionality and features of PCM devices. The plugins deal automagically with jobs like naming devices, sample rate conversions, sample copying among channels, writing to a file, joining sound cards/devices for multiple inputs/outputs (not sample synced), using multi channel sound cards/devices and other possibilities left for you to explore. to make use of them you need to create a virtual slave device.

A very simple slave could be defined as follows:

pcm_slave.sltest {
pcm
}

This defines a slave without any parameters. It's nothing more than another alias for your sound device. The slightly more complicated thing to understand is that parameters for 'pcm types' must be defined in the slave-definition-block. Let's setup a rate-converter which shows this behaviour.

pcm_slave.sl2 {
pcm
rate 48000
}

pcm.rate_convert {
type rate
slave sl2
}

Now you can call this newly created virtual device by:

aplay -D rate_convert test.wav

Which automatically converts your samples to a 44.1 kHz sample rate while playing. It's not very useful because most players and alsa converts samples to the right sample rate which your soundcard is capable of, but you can use it for a conversion to a lower static sample rate for example. A more complex tool for conversion is the pcm type plug. the syntax is:

type plug # Format adjusted PCM
slave STR # Slave name (see pcm_slave)
# or
slave { # Slave definition
pcm STR # Slave PCM name
# or
pcm { } # Slave PCM definition
[format STR] # Slave format (default nearest) or "unchanged"
[channels INT] # Slave channels (default nearest) or "unchanged"
[rate INT] # Slave rate (default nearest) or "unchanged"
}
route_policy STR # route policy for automatic ttable generation
# STR can be 'default', 'average', 'copy', 'duplicate'
# average: result is average of input channels
# copy: only first channels are copied to destination
# duplicate: duplicate first set of channels
# default: copy policy, except for mono capture - sum
ttable { # Transfer table (bidimensional compound of
# cchannels * schannels numbers)
CCHANNEL {
SCHANNEL REAL # route value (0.0 ... 1.0)
}
}

We can use it as follows:

pcm_slave.sl3 {
pcm
format S16_LE
channels 1
rate 16000
}

pcm.complex_convert {
type plug
slave sl3
}

By calling it with:

aplay -vD complex_convert test.wav

You will convert the sample during playing to the sample format: S16_LE, one channel and a sample rate of 16 kHz. As you called aplay with the verbose option -v you see this options as it appears as it comes from the original file. with:

aplay -v test.wav

You see the original settings of the file.

==Software mixing==

Software mixing is the ability to play multiple sound files or applications at the same time through the same device. There are many ways to have software mixing in the Linux environment. Usually it requires a server application such as ARTSD, ESD, JACK... The list is large and the apps can often be confusing to use.

===dmix===

These days we have a native plugin for ALSA called the dmix (direct mixing) plugin. It allows software mixing in an easy to use syntax and without the hassle of installing/understanding a new application first.

A very interesting and potentially extremely useful aspect of this plugin is using it combined with the default plugin name. In theory this means all applications that have native ALSA support will share the sound device. In practice not many applications are able to take advantage of this functionality yet. However if you have time to test and report your findings to the application developers it is worth a try:

pcm.!default {
type plug
slave.pcm "dmixer"
}

pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:1,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}

ctl.dmixer {
type hw
card 0
}

(To use it with your own name just change the word !default above)

Now try:

aplay -f cd -D default test.wav

on multiple consoles.

Some notes:

The dmix PCM name is already defined in the global configuration file /usr/share/alsa/alsa.conf.

- The default sample rate for this device is 48000Hz. If you would like to change it use:

aplay -D"plug:'dmix:RATE=44100'" test.wav

- An example command for dmix plugin to use 44100Hz sample-rate and hw:1,0 output device:

aplay -Dplug:\'dmix:SLAVE=\"hw:1,0\",RATE=44100\' test.wav

- The dmix PCM name is already defined in the global configuration file /usr/share/alsa/alsa.conf.

Defaults are:

SLAVE="hw:0,0",RATE=48000

NB the dmix plugin is not based on client/server architecture, but it writes directly to the soundcard's DMA buffer. There is no limit to the amount of instances that can be run at one time .

===dsnoop===

While the dmix plugin is for mixing multiple output(playback) streams together, if you want to use multiple input(capture) clients you need to use the dsnoop plugin:

pcm.mixin {
type dsnoop
ipc_key 5978293 # must be unique for all dmix plugins!!!!
ipc_key_add_uid yes
slave {
pcm "hw:0,0"
channels 2
period_size 1024
buffer_size 4096
rate 44100
periods 0
period_time 0
}
bindings {
0 0
0 1
}
}

===JACK plugin===

This plugin allows the user to connect applications that support alsa natively to the JACK daemon.

to compile and install jack, you need to move to src/pcm/ext
directory, and run "make jack" and "make install-jack".
this is intentional.

To use the JACK plugin you will need to add the following to your .asoundrc.

pcm.jackplug {
type plug
slave { pcm "jack" }
}

pcm.jack {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}

Now, you can use:

aplay -Djackplug somefile
arecord -Djackplug somefile

===Virtual multi channel devices===

If you would like to link two or more ALSA devices together so that you have a virtual multi channel device it is possible. However this will not create the mythical "multi-channel soundcard out of el-cheapo consumer cards". The real devices will drift out of sync over time. It is sometimes helpful to make applications see for example, one 4 channel card to allow for flexible routing if they can't easily be made to talk to multiple cards (making use of JACK being one example).

Copy and paste the following into your asoundrc.

# create a virtual four-channel device with two sound devices:
# This is in fact two interleaved stereo streams in
# different memory locations, so JACK will complain that it
# cannot get mmap-based access. see below.

pcm.multi {
type multi;
slaves.a.pcm "hw:0,0";
slaves.a.channels 2;
slaves.b.pcm "hw:1,0";
slaves.b.channels 2;
bindings.0.slave a;
bindings.0.channel 0;
bindings.1.slave a;
bindings.1.channel 1;
bindings.2.slave b;
bindings.2.channel 0;
bindings.3.slave b;
bindings.3.channel 1;
}

# JACK will be unhappy if there is no mixer to talk to, so we set
# this to card 0. This could be any device but 0 is easy.

ctl.multi {
type hw;
card 0;
}

# This creates a 4 channel interleaved pcm stream based on
# the multi device. JACK will work with this one.

pcm.ttable {
type route;
slave.pcm "multi";
ttable.0.0 1;
ttable.1.1 1;
ttable.2.2 1;
ttable.3.3 1;
}
# see above.
ctl.ttable {
type hw;
card 0;
}

This will give you xruns, but it's suitable for testing. To test the above setting feed an audio signal to the real sound devices play it back and listen to it with an external mixer:

arecord -f S16_LE -r 44100 -c 4 -D multi | aplay -f S16_LE -r 44100 -c 4 -D multi

To start JACK with the new device, use

jackd [-a] -R [-v] -d alsa -d ttable [-p 1024]

Bindings explained

The above example for a virtual multi channel device uses bindings to make the connections work. The following is a more advanced asoundrc for 2 RME Hammerfalls which is a professional multichannel sound device. Below is a full explanation of how bindings work.

# This is for two RME Hammerfall cards. They have been split into top row
# and bottom row with channels 0-7+16-25 on rme9652_0 and channels 8-15+26-27 on
# rme9652_1. NB. channels 24-27 are used as two stereo channels while the others are mono.

# eg. card1
# | 0 1 2 3 4 5 6 7 |
# | 8 9 10 11 12 13 14 15 24 25|
# card2
# | 16 17 18 19 20 21 22 23 24 25|

What is happening?

There are two sound cards which are linked with a wordclock pipe. That allows them to keep sample sync with each other which is very important for multichannel work. If the sample rates are not in sync then your sounds become out of time with each other.

Each sound card has a number of physical channels 19 + 10. They are represented in /proc/asound/cardx as pcmXc (capture) and pcmXp (playback). Where X equals the number of the physical input/output (i/o) channels starting at 0.

If you look at the lines:

type multi;
slaves.a.pcm rme9652_0;
slaves.a.channels 26;

You can see that the card has been nicknamed "a" and given a range of 26 channels. You can assign the card any number of channels you want but you can only use as many channels as the card has physically available. The bindings start at the first available pcm device for the card ie. pcm0c pcm0p - and move upwards sequentially from there.

The first card for this file has 18 physical pcm devices. Nine of them are capture devices ie. pcm0c pcm1c pcm2c ... pcm8c, each with corresponding playback channels ie. pcm0p pcm1p pcm2p ... pcm8p. The second card has 10 physical pcm devices ie. pcm0c pcm1c pcm2c ... pcm9c.

If you look at the lines:

bindings.0.slave a;
bindings.0.channel 0;
bindings.1.slave a;
bindings.1.channel 1;

The first binding points to the first available pcm device on the card represented as "a". The second binding points to the second available pcm device on "a" and so on upto the last one available. We then assign a channel number to the binding so that the channels on the new virtual "soundcard" we have created are easy for us to access.

Another way of saying it is:

address of.the first channel on my new soundcard.using my real soundcard called "a";
make this address of.the first channel on my new soundcard.be the first pcm device on my new soundcard;

address of.the second channel on my new soundcard.using my real soundcard called "a";
make this address of.the second channel on my real soundcard.be the second pcm device on my new soundcard;

EliotBlennerhassett: compare install with config module list

Grrr. Including category pages doesn't show the list of pages in that category!

Including the pages just gives their fixed text:

----
I took the list of modules from alsa-driver configure --help, and compared with list of modules in this wiki to get these lists.

I think that nobody has full ALSA website map. We need a volunteer which compare the two webs and create a list of missing pages.

--[[User:Perex|Jaroslav Kysela]] 11:19, 3 August 2007 (CEST)

Oh well. I ran a webcrawler over the site, got this list after trimming out the stats etc. alsa-doc stuff is related to the old soundcard matrix?

EliotBlennerhassett: Q about discontinued template

Greetings Andreas.

Great work grinding through all the missing pages!

I have a question about your [[Template:Discontinued]]

Does it really mean that the module development is discontinued, or that the card that uses the module is discontinued?

E.g. many people have the Echo cards - what does original developer Giuliano Pochini <pochini@shiny.it> say?

cheers

Matrix Talk:Tag-RCAio

EliotBlennerhassett: unlink Matrix:Tag-SPDIFio

About the tags [[Matrix:Tag-RCAio|[RCAio]]] and [[Matrix:Tag-TOSio|[TOSio]]]

These are to do with the physical connector rather than the protocol being used.

(We don't call analog connections "XLR" "RCA" "3mm-jack")

I'd suggest a more descriptive tag would be Matrix:Tag-SPDIFio

For instance many [[Matrix:Vendor-AudioScience|AudioScience]] cards support software selectable AESEBU or SPDIF for digital I/O.
The connectors are XLR. They don't have RCA connectors.

EliotBlennerhassett: suggest SPDIFio tag name

About the tags [[Matrix:Tag-RCAio|[RCAio]]] and [[Matrix:Tag-TOSio|[TOSio]]]

These are to do with the physical connector rather than the protocol being used.

(We don't call analog connections "XLR" "RCA" "3mm-jack")

I'd suggest a more descriptive tag would be [[Matrix:Tag-SPDIFio]]

For instance many [[Matrix:Vendor-AudioScience|AudioScience]] cards support software selectable AESEBU or SPDIF for digital I/O.
The connectors are XLR. They don't have RCA connectors.

EliotBlennerhassett: from dev

----
From [https://bugtrack.alsa-project.org/wiki/wikka.php?wakka=CardCm8738]
When I compiled the kernel driver for my CM8738 audio card and start playing on the device I was able to hear only 4 of my 5.1 speakers - the front and the rear speakers.
I have tried all of the alsamixer options and the only thing that I was able to achieve was to turn off the rear speakers by disabling 4-channel mode.

Now I am still looking for a way to listen 5.1 Surround sound with that card.
----
I had this problem. If you enable virtual 5.1 surround sound it works (found in the audio rack settings). Also for me the centre and sub channels were the wrong way around so I had to cut up the audio cable and swap them

==Page creation==

Please, see [[Help:Contents]] for more details, how you can help to create Wiki pages. We need volunteers to move contents from actual ALSA WWW pages here, also we need volunteers to manage contents from others (Sysops) - see bellow (Sysop rights paragraph).

You can't delete a page. If you think a page should be deleted, add it to [[AlsaProject:Requests_for_deletion]] with reasons.

==Old ALSA server==

* [http://www-old.alsa-project.org The current (old) ALSA WWW pages]

{{Note|Warning! The old server is on http://www-old.alsa-project.org URL now!!!}}
==Migration==

* [[MigrationPlan|Volunteers: Look here for a list of pages that need migration]]

==New soundcard matrix==

Please, look to [[Special:WantedPages]] and try to pages started with Matrix: namespace. Please, scrictly follow this document [[Matrix:Description]]. It is better to copy contents from already created pages.

==Sysop rights==

If you like to be an Sysop, please, drop e-mail to perex at suse.cz (try multiple times in case of no response). Please, let me know only to change your user rights. Do not ask me to provide help in context organization - the discussion should go to [[Mailing-lists|alsa-devel mailing list]] or on these pages. Thanks. Jaroslav Kysela [[User:Perex]]
