Thanks a lot for all the help and the information, I must admit this is all a bit over my head but with your help it's not fixed I installed hda-jack-retask (manual compile, I'm running Linux Mint) like they say here : http://lists.freedesktop.org/archives/pulseaudio-discuss/2011-December/012342.html
Then ./hda-jack-retask and I set the Green Headphone, Front side to Override and Not connected, click Apply now, and Set as boot default. I just rebooted and it's working. No more annoying noise now, big thank you. I hope this will be fix in future releases, this problem must drive thousands of people crazy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067434 Title: Sound output device keeps changing when using headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1067434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
