Ok this was more apropriate for the alsa-user list so I repost it here now.
Sorry for not reading the mailing list names mor clearly.

Hi, I am not subscribed to this list but intend to subscribe very soon. I
am having trou	have a general question regarding the GUS max soundcard and
ALSA driver 0.2.0p10.2.

When I attempt to sample with this card, from the microphone, the levels
are far too high and the sound clips. I tinkered with the Mic levels, with no
success. I then looked at /proc/asound/card1/mixer0 but found nothing relivant
there.
Out of curiosity I looked in /etc/asound.conf and found an undocumented
"MIC Gain" setting set to true. I Changed it to "false" and my Microphone
works properly.

My questions:
1: Is this documented somewhere, if so where?
2: Would you like help with the docs? I'm no programmer but the current set
are horrific in my opinion <smile>.
3: What is the proper way to ajust the MIC Gain? Is there an easier way than
editing the asound.conf? Why won't amixer do it? Is there an easier way?
4: What is the "MIC Gain" anyway? I don't see many references to it in 
the driver source, but perhapse grep -i "mic gain" won't do it.
Where would I get documentation on the GUSMAX especially its mixer or what
source should I look at?

Sorry to ask so many questions, but I've been a long-time user of Linux sound
(July 1993) and I'd like to learn how to optimally use this alsa beasty.

PS: amixer is a great util, I hope it stays around, I am blind and the full
screen interface is useless to me.

Regards, Kerry.
