No sound in the debian wheezy?


The system didn't load any sound card modules or drivers:
Quote:
#lsmod | grep snd
<empty>
The lspci show the audio card:
Quote:
# lspci | grep audio
02:01.0 Multimedia audio controller: C-Media Electronics Inc CMI8738/CMI8768 PCI Audio (rev 10)
Quote:
# cat /proc/asound/cards
cat: /proc/asound/cards: No such file or directory
In the sound sittings there is no sound card but instead there is "dummy output"
the pulsaudio and alsa are installed:
Quote:
ii alsa-base 1.0.25+2+nmu all ALSA driver configuration files
ii alsa-tools 1.0.25-2 i386 Console based ALSA utilities for
ii alsa-utils 1.0.25-3 i386 Utilities for configuring and usi

Are you using a custom kernel? If yes, make sure the modules for your sound card are included/loaded, otherwise ignore this part.

Then use the command alsactl init to setup the card. Also check the volume on alsamixer, sometimes it is set all the way down.

I had a similar card and after a few hours of troubleshooting I finally solved it.

Open /etc/modprobe.d/alsa-base.conf

Find:

Quote:
options cx88_alsa index=-2
change it to:

Quote:
options cx88_alsa index=0
and restart.

I don't know if it will work for you, but you had to try it. I had a c-media card too.

Tr installing all new drivers from main site of alsa.

After searching for several hours this solution works for me like a charm.
