Description Dergan 2023-08-29 19:33:26 UTC

Application: plasmashell (5.27.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-11-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [CoredumpBackend]

-- Information about the crash:
Plasma sometimes random crashes so maybe the backcontent shows that
But I/myself setted the audio output from
HDMI / DisplayPort (Built-in Audio digital stero (HDMI)) > HDMI / Displayport (TU102 High Definition audio controller Di...)

And then it simply crashed

The crash can be reproduced sometimes.

Comment 3 Nate Graham 2023-09-07 18:36:47 UTC

I'm not seeing any KDE code implicated in the backtrace and I suspect a distro configuration issue. Can you report this to the Debian folks? Thanks!
