Package: wireplumber Version: 0.4.13-1 Severity: normal Dear Maintainer,
On this Debian 12 (bookworm) system, sound output in the GNOME and Wayland desktop environment became unavailable recently. The only output device listed in the 'Sound' panel of gnome-control-center is 'Dummy Output'; however, multiple devices are listed in the output of the 'aplay -l' command: **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: CX20753/4 Analog [CX20753/4 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 ... The following entries are present in the system journal for wireplumber, as produced by running 'journalctl --user --merge --unit wireplumber': wireplumber[pid]: Failed to connect to session bus: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11 wireplumber[pid]: Error acquiring bus address: Cannot autolaunch D-Bus without X11 $DISPLAY wireplumber[pid]: <12-digit-hex>: leaked proxy <12-digit-hex> id:<integer-id> wireplumber[pid]: disconnected from pipewire As a workaround, running 'wireplumber' from the command-line (using the logged-in user account) restores the expected behaviour: sound is emitted again, and audio output devices are listed in gnome-control-center.
