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!
