I have a Bose Soundbar 700. It is connected to my TV via the ARC HDMI. It works absolutely fine, if I then connect spotify via my phone the Bose correctly switches to Spotify. However, once I disconnect Spotify via the Spotify App, the Bose 700 will not reconnect to my TV. I end up having to switch everything off at wall and eventually the Bose reconnects with my TV.
