I've set up a new PC using Mandrake 9.2. The onboard sound chip was correctly detected and installed. The modules are loaded, the sound-devices exist, /proc/asound/ looks ok, alsamixer is working fine, but...
... there is no sound output from PCM. Playing back a CD through analoug soundcard input works, I can e.g. control CD volume in alsamixer.
I've tested play, aplay, xmms/oss, xmms/alsa.
xmms hangs when I hit the play button. Seems like the soundcard doesn't start processing.
This is a ASRock K7S8XE Mainboard with onboard sound which works under win2k correctly.
The codec is shown as "C-Media Electronics CMI9739" in alsamixer (which is the correct name).
The only thing that doesn't look good is /proc/interrups (see attachment). The SiS SI7012 should be the sound chip, so I assume the counter shouldn't be 0.
I've attached the output of the aadebug script, maybe it's of some help. What should I try next? Thanks in advance!
