pulse audio does not load because "module-switch-on-connect" should be loaded once at most

[janl]

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.
  Refusing to load.
  E: [pulseaudio] main.c: Module load failed.
  E: [pulseaudio] main.c: Failed to initialize daemon.
  $ ps auxww | grep pulse
  niclangf 9833 0.0 0.0 15900 1036 pts/3 S+ 15:16 0:00 grep --color=auto pulse

Removed .config/pulse and .gconf/system/pulseaudio
