hello,

this device

http://www.cmedia.com.tw/product/CMI9761.htm

the -A- type ive got

has working continuous (slider) master mixer+balance and "working" pcm
mixer slider with v106 (2.6.10 release kernel alsa) but no more with
v108 alsa-driver or cvs from yesterday.

please branch for this device (on cheap asrock mass-seller K7VTA+ board
with via8235 pci).

- -worse: pcm playback not working, capture works, seems no muting
problem, klick sound on switching pcm mixer.

10 days left to fix it, or the board returns to the shop.

need a start point for pcm problem, please. somebody got a reg
descrption? only harware datasheet is available from vendor.

?

Interesting.  How can one detect the difference of model?  Does it
have a different codec id?

Anyway, please attach the contents of /proc/asound/card0/codec97#0/*
files.

No.  We have no datasheet for these codecs at all.

Well, I'm working on the problem of CM9761 (model 83) with another
guy.  We found out that although the Master and PCM volumes look as if
working, they don't affect any volumes in fact.  So, removing these
controls are correct (at least for his chip).

Please make sure that the Master and PCM volumes _really_ work with
the older version of ALSA on your board.  That means, when you change
the PCM or Master volume, it really changes the output level.

Anyway, the patch below might fix the silent output of CM9761, which
was already committed to CVS today.

Re: [INFO] C-Media CMI9761 -A- type , CODEC ID BY MB

[Sergio Monteiro Basto]

Hi,

After search on https://bugtrack.alsa-project.org/ for CMI9761, 1
issues, resolved ! 
with some similarity is one ASRock k7vt4a+ with CMedia CMI9761, I have
one ASRock P4VT8+ with CMedia CMI9761.

After play around with alsamixer, 
I got sound when unmute PCM and Off (mute) IEC958 Capture Monitor.

All others controls does change anything include mute or unmute the
Master.
Except VIA DXS (this one can do sound balance, left and right).  
VIA DXS 1, VIA DXS 2 and VIA DXS 3 also doesn't do nothing.

Play around with 
options snd-via82xx dxs_support
on file /etc/modprobe.conf
only with "options snd-via82xx dxs_support=2" I see any difference but
for worst, make disappear VIA DXS, VIA DXS 1, VIA DXS 2 and VIA DXS 3
controls.

So, can help you testing alsa CVS ?
Now I have to sleep and tomorrow, I am a little busy but, have you some
patch in specific to test this C-MEDIA sound card ? 

Sorry for my weak English, if you don't understand something just ask
me, that I will try explain again.

thanks,
