Sound Notification: Fix Node Suspend on Idle (Bluetooth battery drain) (

wbolster#74) Enabling "Sound notification" seem to cause Bluetooth battery drain. It seems the mic on/off sound state doesn't get reset after playback; audio source state is still "Running". Fix resets playback at end-of-stream, so Pipewire can auto-suspend node (e.g. Bluetooth headset). Co-authored-by: Kok-Yan Lo <[email protected]>
