After X does something (i.e. doing a ls in an xterm), the sound output is
garbled for the next few seconds and then vplay (.wav files) or cat (.au's
straight to /dev/audio) dies with an i/o error and the "sound: DMA output
timed out. IRQ/DRQ error?" shows up in the logs. Defining NO_SB_IRQ_TEST
doesn't help the problem.
