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. -- sound volume always resets to 100% after reboot https://bugs.launchpad.net/bugs/204536 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
