Since this bug was fixed for the original reporter, I'm marking it as "fix released". In order to minimize confusion: if you're still having a problem, it's a different root cause, and so I'd kindly ask you to file a new bug, e g by opening a terminal and entering the 'ubuntu-bug audio' command which will guide you through the bug reporting process. Thanks!
