Yes, I use ALSA, which is compiled into the kernel.  If it is alsa, how would I go about tracing the problem.

------------8<------------->8------------
Advanced Linux Sound Architecture Driver Version 1.0.4 (Mon May 17 14:31:44 2004 UTC).
ALSA device list:
   #0: PowerMac DACA (Dev 6) Sub-frame 0

Here is another oops straight from my system's logs.  This one isn't
pbbuttonsd, but is alsamixer.  Would compling ALSA as modules help? I could
then unload them when suspending...
