This is strange!?
I have a HomeKit home and Apple Music.
The symfonisk are visible in home app.
If I make a shortcut to play music directly to my symfonisk speaker and run it, then Apple TV hijacks that and stream to my speakers.
If I then wants to watch a show on my tv, then the music pause, and plays the sound through my speakers.
I can not watch a show with audio on the tv speakers and play music on the same time on the symfonisk.
They are not in the same room !???
If I play directly to the speakers from Sonos app, then I can watch a show on Apple TV at the same time.

Solved by logging out and back in to iCloud.
Now Apple Music can see the speakers directly.
