When unplugging a usb camera that has a built in microphone, gnome-shell crashes. If I disable the plugin, gnome-shell doesn't crash.

@Connor9220 Could check if your pulseaudio daemon crashing when you disconnect your microphone?

meaning:

  • disable the plugin,
  • check the start time of pulseaudio
  • unplugg USB camera with microphone
  • check if the start time of pulseaudio is different.

pulseaudio isn't affected. It stays running.
I disable the plugin, I can plug/unplug the USB camera with microphone without gnome-shell crashing.
I enable it, unplug it then crashes.

systemd will spawn a new pulseaudio if the current one crashes, did you verify by looking at the start time that it's the same time?

I have confirmed. pulseaudio has the same start time and pid as before the crash. It's stable.

I assume this is caused by the same bug reported here: https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/issues/9

I have exactly the same issue when disconnecting/turning off my USB DAC. Gnome-shell crashes immediately.

This prevents calling a C function with an old pointer from the JS
timeout callback which then crashes the GNOME Shell.
An upstream fix was also sent in which prevents the crash of GNOME
Shell but still this bug here needs to be fixed.
