            Bug ID: 380411
           Summary: Plasmashell hangs waiting for audio
           Product: plasmashell
           Version: 5.9.4
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: generic-crash
          Assignee: plasma-bugs@kde.org
          Reporter: Paul.Hancock.17041993@live.com
  Target Milestone: 1.0

If pulseaudio becomes unresponsive or is in a bad state, plasmashell can hang,
leaving the entire graphical system unresponsive unless you can kill and
restart pulseaudio.

This condition can occur when messing with jackd or if a device encounters an
error or similar condition, of which if the user attempts to adjust the volume
or trigger a plasma audio event, plasma will immediately hang indefinitely.

Audio calls need to not be blocking, or should be handled in a sandboxed thread
with a timeout, there is no guarantee that they will finish immediately or at
all (hence why window's did away with push events).
