No sound in the debian wheezy?

shams · 01-16-2013, 11:43 AM

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:

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.
