Sound driver bug (?)

Here is a bug I have seen in the 2.0.31 sound driver. This is with a
PPro200 a SB32.

First, in 2.0.31 (possibly 2.1.xx also) the sound driver seems to have a
problem. If I have a 'partial buffer under-run' (eg, playing mp3s off of a
(SCSI) CDROM while some big program loads...) it sounds like part of the DMA
buffer gets corrupted, and doens't get overwritten the next time the buffer
cycles, causing a repetitive clicking noise. Stopping output (putting the
mp3 on pause) for long enough to finish writing out the buffer the resuming
seems to clear this problem.

This has happened with multiple programs, so I don't think it is a problem
with the player (also because of the symptoms)
