Running twm, mpg123 in an xterm, and Mozilla with X niced to 0, the sound still skips when I scroll in Mozilla.
The skipping even happens with "play" (wave file player), and this machine is grossly overpowered for just playing music and running X, so I doubt it's a CPU time issue. I'm actually running Mandrake 9.0 on the machine in question, and X started out niced to -10. Also, I forgot to mention earlier that I've ruled out an IRQ conflict. Theoretically, since they're both PCI devices, the sound and video cards should be able to share an IRQ, but I moved the video card around to ensure that they're on different IRQs.
