Problem reappeared for me since Linux Mint 18. I now run LM 19 Mate and again, problem is there. I can see the sound fluctuating in Sound Preferences / Input and pavucontrol / Output Devices and alsamixer.
In alsamixer, my loopback is already disabled so it's not a solution for me. For an unknown reason, the hda-task-rejack solution is not working anymore, after a reboot, the changes are gone. It's like it's never being saved after clicking "Install boot override". My last solution is to leave a jack cable into the front microphone of my desktop tower which solve the problem. -- 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
