I have this with a creative xfi on 9.10 64bit. Killing the the .pulse dir resets the issue and I'm back to normal. However changing volume seems to be causing it for me. Including setting the volume to max (via the desktop slider).

I run at 5.1output with mono input. Previously to work around, one my audio was corrupted, I would change to 4.1 output and that would work until it got corrupted, then I'd change to something else. Once my audio is corrupted though it stays corrupted (in that config). I get the same rattle sound, although to me it sound more like high frequency aliasing. Like when you try and record a 22khz sound when your sample rate supports say only sound up 8khz. It sounds like artifacting. I did not have this issue in 9.04.

There may be an issue with the flash plug in corrupting my sound as well but I don't have a reproducible test case. Now that I can correct my 5.1 audio I should be able to add a test case. Thanks for all for looking into this.
