C-Media 9880 : No sound except 2.1
Hey,
I have a ASUS P5GDC-V motherboard with C-Media 9880 Onboard high def audio. alsaconf setup my sound with the snd-hda-intel module and everything is working fine. Then I tested out new 5.1 speakers and found that I was only getting output for the front 2 speakers and the woofer. No output was coming from any of the other channels. I get output on all channels in Windows. The alsa documentation in the kernel states in the snd-hda-intel part : Quote:
Anyone manage to get C-Media to output on all channels in their linux boxes ? the sound works fine in windows, so its not a H/W problem. Another thing, I don't know whether this is related.. I don't have any file named /dev/dsp or /dev/audio . I am on kernel 2.6.23 .. self compiled . I tried Quote:

Hi duryodhan, You might try adding the following to your /etc/modprobe.conf.
Code:
options snd-intel-hda index=0 model=full_dig |
Hey
It seems to be working fine now ... I will have to get some true 6.1 movies/mp3s to check it fully ... but in normal mp3s some sound is coming from the other channels too thanks a lot!! I realise why you added model=full_dig ... but why did you add index=0 ? |
and shouldn't it be snd-hda-intel ?
lsmod gives Quote:
Also, I added it to /etc/modprobe.d/sound as modprobe.conf is deprecated , just thought you would like to know ... |
For future reference, use something like this to test:
speaker-test -c6 -Dsurround51 -t wav |
