i m using a creative extreme gamer sound card and when i set SB X FI to 5.1 or 4.1 and change the volume or change the balance between front and rear than that causes it to put out to the normal sound withe high pitch noise.
I m using ubuntu 10.04 and the same bug a cured when i was using ubuntu 9.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:
apport-collect -p alsa-base 589316
This will help us to find and resolve the problem. Bear in mind that you may need to install the python-launchpadlib package from the universe repository. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report. Thanks in advance!
When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https:/
