Sorry for cross posting, I am replying to 2 different threads 1 is alsa-
user and other in alsa-devel!

Please cc to me!

Like Jakob Schurdak, I reinstall alsa from CVS (alsa-driver, alsa-lib,
alsa-utils),  that already have Takashi patch,  but the mixer still have
exactly the same behavior. 

I have one ASRock P4VT8+ with CMedia CMI9761 (not the same of Jakob) but
same rev. of sound card.
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)

Applying this patch from Thomas Schorpp, I have a better mixer and don't
have mute nothing as before, I just unmute PCM and have sound, Master
volume appears but don't have any effect when mute or unmute or change
volume.

For me, try to set up a PCM config manually on my own ~/.asoundrc ,
doesn't change noting ( unless when I forget close  "}") :)

thanks and regards,

uh-oh :)

i code with too much drink and the users like it, great! :]]

... sergio, this patch is crap, pls pull cvs with attached revisions and 
tell if your master vol works then.

my does. and so balance.

THEN update to head and apply both patches attached further below from 
takashi and report (especially if you get pcm sound after unmute of "iec 
capture" switch.)

Re: C-Media CMI9761A REV

[Sergio Monteiro Basto]

Hello,
Alsa-webmaster please read the end of message and improve your
http://www.alsa-project.org/download.php page !

Well mine is:
lspci -v
00:11.5 Multimedia audio controller: VIA Technologies, Inc.
VT8233/A/8235/8237 AC97 Audio Controller (rev 60)
        Subsystem: ASRock Incorporation: Unknown device 9739
lspci -n
00:11.5 Class 0401: 1106:3059 (rev 60)

I finished to test last sources of the CVS, I back to first state, no
improves, no master again.

For Jakob and alsa-webmaster, a little fast How to compile alsa from
CVS:

yum -y install gettext-devel.i386 ( you will need this for cvscompile
alsa-utils and you will need autotools ) 

service alsasound stop (or rmmod all snd-*)

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/alsa login
(enter)
cvs -z3 -q -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/alsa co alsa-driver
cvs -z3 -q -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/alsa co alsa-kernel
cvs -z3 -q -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/alsa co alsa-lib
cvs -z3 -q -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/alsa co alsa-utils
cd alsa-driver
cvscompile (stop when enter in configure, because will compile drives
for all cards and we just need for our via82xx) 
./configure --with-cards=dummy,via82xx --with-sequencer=yes --with-isapnp=no
make
make install
modprobe snd-via82xx

cd ../alsa-lib
cvscompile && make install && ldconfig
cd ../alsa-utils
cvscompile && make install
