Public bug reported: This laptop was initially loaded with kubuntu 17.04. Yesterday I used do-release-upgrade to update to 17.10.
This morning I noticed that the pulse audio mixer was broken while chrome and amarok could still play sound. Cold booted just in case. Still no pulse mixing. But alsamixer was working. Found that no pulse processes are running. $ ps auxww | grep pulse niclangf 9666 0.0 0.0 15900 1180 pts/3 S+ 15:13 0:00 grep --color=auto pulse $ pulseaudio E: [pulseaudio] module.c: Module "module-switch-on-connect" should be loaded once at most.
