Comment 18 for bug 64356

Luis,
This bug was filed aegainst an old, no longer supported kernel. The sound subsystem has undergone significant change since that time. Please follow the directions below and file a new bug and include your specific hardware and release information if you continue to have a sound problem.

Can you also confirm this issue exists with the most recent Karmic Koala 9.10 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Thanks in advance.
