[tlinux-users:08556] Tips for debugging sound problems?

Ubuntu 7.04 continues to work great on my Satellite.  I am, however,
having one problem with sound:

The right speaker channel, both with the built-in speakers and with
external ones, sounds fuzzy and distorted, as though there were a loose
wire.  However, the sound is fine in Windows, so it's not a hardware
problem.  It happens with YouTube videos under Firefox and with Rhythmbox,
so it's not just one particular piece of software.

Does anyone have any suggestions for how to go about debugging the
problem?  I'm at a loss.

Thanks,
crism
