Bug ID: 433415
Summary: Plasma shell crashes when messing around application
audio settings in tray fly-out
Product: plasmashell
Version: 5.21.0
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: goldenhash...@outlook.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.21.0)
Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.10.16-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.21.0
Distribution: "openSUSE Tumbleweed"
-- Information about the crash:
When used together with PulseEffects, messing around output settings via audio
tray causes Plasma shell to crash.
Plasma shell version is 5.21.0. This issue won't occur in previous version
(5.20 ?)
Steps to reproduce:
1. Install PulseEffects and make sure it's running;
2. Enable some random effects;
3. Use whatever music player you like to play a music (This is necessary to
reproduce; silent status won't make plasma shell crash; For me VLC and Lollypop
can reproduce this)
4. Open volume tray fly-out, switch to Applications tab (this is necessary,
crashes won't occur when you mess around settings in Devices tab), find the
music player that is playing music, change its output device to hardware
output, then change back, repeat this process for mutliple times, then switch
back to Devices tab, Plasma shell should crash now;
5. If above steps won't crash Plasma shell, switch to Applications tab, in
additional to step.4, also change PulseEffects application volume and output
device repeatedly, then switch back to Devices tab, Plasma shell should crash
now.
Above step reproduces for both my laptop and desktop, one is upgraded to
5.21.0, another is clean reinstalled to 5.21.0, both running openSUSE
Tumbleweed.
This issue won't occur without PulseEffects, however an audio post-processing
software that routes output devices crashes Plasma shell indicates complicated
audio output setup isn't handled well.
The crash can be reproduced every time.
