I'm reading through the documentation, and I'm still not 100% sure if this
is even supported:

Basically I want to be able to play multiple things at once.. is this your
"Virtual PCM device" thing? Is it included in the 0.2.0-pre10p1 version of
your driver? I can't seem to figure out how it works. Oh.. and I know you
don't maintain the mpg123 port for alsa (maybe someone could pass this
along..), but it's miss-documented.

The format of the mpg123 command is as follows:

mpg123 -a 1:0 <filename> <--- this is what actually works.
       ^^
not 

mpg123 -o 1:0 <filename>  <--- this is what it says in comments in the patch.
       ^^
which is what it says in the documentation. Just an a instead of an o.


Anyhow.. at the moment I only seem to have one PCM device, and I can only
write to it from one application at a time. How can I get these "virtual
pcm" devices that are spoken of in the documentation?

thanks,

-Rob.
