Bug Description

After listing to some music with my headphones, using the front line out (headphones) jack of my computer, I lost the stereo sound on my speakers. The speakers are connected to my receiver which is connected with my computer (with a line out jack at the backside of my computer). Restarting the alsa server with "sudo /etc/init.d/alsa-utils restart" didn't help. I got the stereo-sound back one time after losing electrical power on my computer for 15 minutes. But after using the headphones again, I again lost the stereo-sound on my speakers. A new powerflip did'nt work.

Using: Ubuntu 7.04

I also reported the problem on the Ubuntuforum:

I used the line out jack at the front of my computer for a while so I had stereo sound. In this case my receiver is connected with the front line out jack.
I just changed the situation back and connected the receiver to the line out jack at the back side of the computer and got my stereo-sound back! So its (temporary) solved.
I still believe there is a bug. The next days I will listen to my headphones again and see what happends.

Thanks so far.

Front line out jack works fine, the one at the back side of the computer doesn't.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for this particular version of the kernel. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .
However, the issue that you reported is one that should be possible to test with the live environment of the Desktop CD of the development release - Gutsy Gibbon. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed kernel. You can find out more about the development release at http://www.ubuntu.com/testing/ .
If you do decide to test with the development release of Ubuntu please comment on this bug report and include at least the minimal information requested at http://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help.
