Do you still get the issue? Could you install libglib2.0-0-dbg and get a
new stacktrace? It would also useful if you could do:
- gdb gnome-control-center
(gdb) run sound
... you should hit the bug and gdb should stop
then type "frame 6"
(or whatever number correspond to that code line: #6 0x00007fffc8cfc49a
in gvc_mixer_control_lookup_device_from_stream
(control=control@entry=0x555555af2690,
stream=stream@entry=0x5555559e3570) at gvc-mixer-control.c:229)
then type "print *device"
** Changed in: gnome-control-center (Ubuntu)
