Title:
Crash switching audio output while playing audio in Audacity
Status in alsa-driver package in Ubuntu:
Invalid
Bug description:
Following the steps below, i get a crash and KDE Plasma doesn't show any
audio output device on my system. I have to reboot the PC to make it work again.
I can reproduce 100% of the times in Kubuntu (installed and also using the
Live ISO). I can't reproduce it on Ubuntu standard, so it seems to affect
Kubuntu only
I have a PC that is connected to the HDMI screen and to the earphones
via audio jack. So I have 2 outputs: HDMI + Earphones.
1) Put the audio output to HDMI
2) Play an mp3 file for few seconds to check everything works
3) Open an audio file in Audacity
4) Play the audio file in Audacity
5) While playing, change the audio output to earphones.
I attach the output of journalctl if it can be useful
