Apple TV audio output keeps changing and I have no sound
Power outage. Apple TV no audio. Reset device. I have a Sony Bravia using a Sonos Beam. Audio output says default "Receiver/speakers" but no sound unless I manually set to the Beam. If I pause a show using Apple TV, the sound quits. I can't get the audio output to revert to TV speakers. (It doesn't come up as a choice.). If I unplug the Beam, the Apple TV sound works through the tv speakers.). Also the Apple remote, which worked with the Sonos before, will no longer control the Beam when viewing show via Apple TV.
Apple TV 4K, tvOS 15
