I find realplayer unusable on this hardware.  Alsa sound works fine, but
realplay uses oss.  The sound is unusable, because it is so choppy.  I
tried kde control-center/sound system, and tried setting a larger buffer,
but no good.

I have quite a few other computers with different sound hardware on which
the exact same test works fine.

Any ideas?
 
1. If you have less than 512m memory in the affected box increase to at least 512m.
 
2. Look into the interrupt structure (and bus master issues) on your PCI bus.  Perhaps the sound HW has a lot of competition??
 
3. Consider using "nice" to make the soud applications and drivers have more access to the processor time.
 
4. Install a low latency kernal (see: http://ccrma.stanford.edu/planetccrma/software/ ).
 
Enjoy!
