I've done a little more digging and I'm not sure this is a bug in
pulseaudio, or a bug in alsa-lib. After poking around pulseaudio with
gdb for a while, I narrowed down the line where the extra file handles

I'm not sure how to go about doing this, could you provide me with some
pointers or a starting point? Deleting my log files and doing
"pulseaudio -k" is getting somewhat old, and it makes my CPU run like
crazy, thus making my fans step up to maximum and also getting to be
very loud.

Right, so you are using glitch-free. Let's see if we can narrow down
whether it's linux or PA at issue, or possibly both. There are
definitely workarounds for either/both.

I haven't the slightest clue what you're asking. I'm using PulseAudio
as it comes with Ubuntu, configured for my number of speakers using the

I suppose I can find out, but if the problem is dependent on the kernel
to be triggered, then this PA bug is a much larger bug than it would
appear to be; P
Is this symptom reproducible in the Ubuntu Karmic kernel
