I've only been running Linux for a year. Running Debian Squeeze, AMD64. I watch/listen to video clips, mostly on political blogs. IceWeasel is the browser. Adobe Flash Player non-free plug-in is installed. About three weeks ago, the audio became garbled, with unintelligible noise that goes from high to low volume at about 2 Hz. A reboot fixes it. 18 hours later it still works. By about 24 hours post-boot, the problem recurs. The system plays CDs well even when the audio clips won't play. Audio-only clips have the problem.

I'm also trying to figure out a problem with "Volume /tmp only has ??? Mb free".

I am at a loss for ways to begin to trouble shoot this problem, or even to be able to succinctly describe it for a fruitful search.

Any ideas?

Thanks.

did the audio problems start when you started getting messages about /tmp running out of space? The 2 problems could be connected. /tmp gradually gets files added and a reboot does clear out those files. Can you post the output of the df command? That may help diagnose the problem.
ciao,

edit: I just read your other thread. I'd suggest following the advice there. It may clear up this problem as well.

On Sunday, I believe, Debian made available upgrades to Squeeze, to go to version 6.0.3. Since upgrading, the problem has ended. Thank you for the comment.
