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-b...@kde.org
Reporter: paul.hancock.17041...@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).
