Comment 29 for bug 269027

I've looked at this bug, and to me it appears to be a collection of related issues, especially because people are having success with different solutions, depending on their devices. I've marked the bug invalid, as I don't believe there exists a solution that definitively closes the bug for all participants.

Could those experiencing the issue please retest against a current image (alpha, beta, daily, etc.), and if the problem recurs, open new (separate) bug reports following https://wiki.ubuntu.com/DebuggingSoundProblems ? The goal is to have one report per specific hardware device demonstrating the issue, as it is likely that each requires different quirks to reach a solution.
