I managed to configure sound in OpenSuse 11 on a M3N-HT motherboard with onboard sound. The codec is AD1988B.
The sound is highly distorted. The speaker test would run like
‘front ont ont ont … left eft eft …’, with a lot of noise.
I followed the guidelines in the SDB:AudioTroubleshooting article.
Alsa packages have been upgraded to the last versions. However, I see that the firmware package is still at version 188.8.131.52git20080617-3.1 while there seems to be a version 1.0.17 already (on the alsa-project website).
Below is the detailed output of all steps described in there.
Note that the model option specified in /etc/modprobe.d/sound is now 6stack-dig, but I get the same results with 6stack as model option. In fact, the motherboard has an spdif output, but I do not know if its linked to the onboard sound card.
I have removed PulseAudio, and returned to esound.
There is another thread describing almost the same problem, however I have the impression that this thread is dead (or at least dying), so I’m creating a new thread here.
Here’s the detailed output
