Do you have the Alsa apps such as aplay, arecord, amixer, etc.,
installed?  If so, type "aplay -l" and see if any soundcards are found.
This is what I get:
   [mcallman at prez doc]$ aplay -l
   aplay: device_list:205: no soundcards found...

I also lost the sound output, although not all.  I can play a ".au" file
directly to the /dev/audio device (cat > /dev/audio) and I hear
it.  I'm working on finding the solution.  I've posted about it here but
haven't had any luck.  It's something with the "pcm" devices (whatever
they are), I think.  I've never fiddled with anything audio before so
it's all new to me.
