Comment 36 for bug 204536

I am experiencing the same issue on my laptop using karmic ubuntu studio, the issue is definetely pulse audio. I installed ubuntu studio alplha version and had a lot of issues with sound. I purged pulse audio from my laptop and everything was fine, after a reboot my sound settings would be OK.

I reimaged, this time using the ISO for karmic ubuntu studio and my machine now has the same issue, volume is all the way up after a reboot.
