I have the same issue with my ALC892. The only workaround is to use the hdajackretask, however this tweak disables either speaker or microphone.
Does someone know if this bug will be fixed as it have been reported in 2016 ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577599 Title: [CM1855, Realtek ALC892, Green Line Out, Rear] Sound is distorted / Audio Notification unstable (Popping in/out) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1577599/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
