I have a Dell OptiPlex GX1 that had Mandrake 8.2 installed and sound was
working (using a previous ALSA version - 0.5.12a I think). I upgraded
kernels and ALSA and sound stopped working. At first, I only thought I
had one change to make (snd-card-cs4236 ---> snd-cs4236) in
/etc/modules.conf. That failed to work and I am at a loss to figure out
why PCM audio is not working. I can successfully play an audio CD and
output the sound through the sound card, controlling the volume with an
OSS mixer -- at least that part works. I get no PCM sound and all the
MIDI players I try crash. I alsoget errors running aplay or alsamixer.
Perhaps someone can look at this and tell me what I'm missing.
The modules all insert cleanly (no errors or warnings - verified with a
'modprobe -d'). After 'modprobe cs-4236', I issue 'modprobe snd-mixer-oss'.
