I've been having this problem for some time:
when changing the volume, scrolling text, moving windows, and on various other actions performed in X,
I get a buzzing sound in the right audio channel.
It's so annoying that it's about to drive me crazy.
I tracked down the problem to OpenGL in X (don't ask how, intuition
when the GLX extension is enabled I get this annoying problem.
When it's disabled the buzz goes away.
This is rather strange in my opinion. I'm not sure how GLX interferes with sound performance...
Slackware 10.2 pretty much upgraded to current
Sound Card: VIA 8273
Video Card: Radeon 9200
Any idea how I could go around this problem would be appreciated.
