I get horrible screeching with timidity++, myself.  MP3s and other audio
sounds fine, though.

Interesting.  The nVidia nForce3 already uses a default buffer size of
16384; I just rebooted, setting it to 32768.  Will see if this has any
benefit or not.  <crossing fingers>

I've tried fiddling with hw.snd.targetirqrate, but that did no good. 
Still broke after a while.  <sigh>
