[SOLVED] Bluetooth needs reconnecting after using Spotify connect

[Tim Curtis]

The audio renderers are independent playback applications and unless they release the audio output when not playing or not connected then other renderers won't be able to play or maintain their connections.

IIRC Spotify Connect, Bluetooth, Squeezelite and RoonBridge do not release the audio output. Only Airplay does this after a 10 second timeout. MPD also releases the audio output. This is what enables a renderer to interrupt MPD playback.
