Thanks for your bug report. Given the symptoms you have described, I am pretty sure this is a duplicate of bug #741825, so I will mark it as such. Please feel free to read that bug to get a better idea of the problem, but in short, recent changes to audio code in Ubuntu 11.04 have exposed a chipset bug.
