Duplicate items and crashes in gnome-shell audio output selector after pulseaudio/pw-pulse restart
Restarting Pulseaudio or Pipewire can result to duplicate entries appearing in the audio output selector in the gnome-shell menu.
Changing the audio output in this menu after PA/PW restart, can crash gnome-shell with traceback as noted in libgnome-volume-control!22 (comment 1790558)
These issues should be fixed by bumping subprojects/gvc to commit libgnome-volume-control@f3806ad5 or to the current master which includes it.
