With my headphones jacked in, the line out and headphones output options keep switching automatically, resulting in crackling (and broken audio). I have tried many solutions I found online but none of the suggested fixes work. I am attaching a video of what I see (note that this happens automatically, I don't click anywhere) This is not a hardware issue (the headphones work fine on another machine running Ubuntu 16.04, and as far as I'm aware this problem only appeared after I upgraded from 16.04 to 18.04). $ lsb_release -rd Description: Ubuntu 18.04.1 LTS Release: 18.04 I have uploaded two different videos showing what I see here: https://youtu.be/S49cEC5DRsk https://youtu.be/zSfi5ko5nBY --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jp 5422 F.... pulseaudio /dev/snd/controlC1: jp 5422 F.... pulseaudio /dev/snd/controlC2: jp 5422 F.... pulseaudio CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=84a04536-72b0-461c-99b3-6dd8190bd471 InstallationDate: Installed on 2016-05-12 (992 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) IwConfig: docker0 no wireless extensions. lo no wireless extensions. enp4s0 no wireless extensions.
