FWIW, I'm currently running testing and kernel 2.6.15-1 on a
Sun Ultra 10 with the CS4231 sound chipset.

These are the same symptoms that I had with a previous 2.6 kernel,
although I don't remember which one, other than I believe I skipped
2.6.14. I don't use xmms, but all I got from ogg123, mpg321, and
mp3blaster was noise. Sound is working for me again with my
current kernel.

My lsmod looks like exactly yours (except for the sizes), although 
for some odd reason I have this, but I don't know if it matters.
  snd_mixer_oss          19072  2 snd_pcm_oss
All I have in /etc/modules is snd-sun-cs4231 and snd-pcm-oss.

I never investigated beyond simply changing kernels, so I can't 
help with this.
