Subject: [PATCH 1/1] Release the sound card at the end of the session

PipeWire keeps the sound card open for a few seconds (the WirePlumber
node suspend timeout) after the playback stops. When logging out while
playing music, the greeter starts in the meantime and its PipeWire
cannot open the card, so the greeter's sound is not played.

Suspend all sinks once all graphical units have stopped. The suspend
only closes the card, the next playback opens it again.
