I had this problem when I had headphones connected to the front jack and simultaneously the line out at the back connected to my amp.
I solved it by using hda-jack-retask that Raymond mentioned above. Using advanced override I set "Green Headphone, Front side" > "Jack detection" to "Not present". Then "Apply now" which solved the problem immediately and also "Install boot override" which made it permanent. Let me know if you want me to provide any information. -- 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
