Comment 3 for bug 61211

I had the same problem and I think I know how I produced it:
Hardware:
IBM Thinkpad X24 with Onboard soundcard "Intel 82801CA-ICH3", running Ubuntu 6.06.1

Audio was working properly until I attached an external USB headset. I've tried 2:
One Logitech and one from CMedia.

Logitech didn't work, but CMedia did - so I selected CMedia headset as sound device from "System > Preferences > Sound Preferences"

I only had this headset attached temporarily.

Now sound in gnome is behaving quite strange:
- sound during boot: yes
- sound in Totem: yes
- sound recorder: no (with error)
- audacity: no errors, but recording is broken and played back in other players with bad resampling artefacts.

I'm still having this error so maybe I'm lucky and can find out how to fix it.
