Since about 3 days ago, after a certain period of time of using the audio output (whatever the program, either totem, vlc, flash, and whether with a single user connected since boot or with a second user session opened) the audio changes abruptly to a mix of cracks and rings (listen to the attached audio output). Nothing seems to correct the problem, even though I've managed to get the audio back to normal once by closing all audio applications for a while and trying again.

The computer has an ICH10 Intel controller (GB EP-45 DS4). The computer is also affected by bug #433654, but the problem reported here wasn't there before (using Karmic since Alpha 4) and appears even if only one user is connected after boot.

I've left Totem open with the problem while reporting the bug with ubuntu-bug. Computer has all updates, and was just booted 20 min ago, with Totem playing audio for about the same time before the problem occurred, and a single logged in.
