I have Apple TV 4K, latest tvOS, HDMI output into my receiver. Never had a problem until I recently added an Ikea Symfonisk (Sonos under the covers) speaker in another room.
Now the Apple TV keeps re-pairing with Ikea speaker, such that the audio output is going through both the HDMI in the TV room simultaneously with the speaker in the other room. I can go into Video/Audio settings and un-check the Ikea, and it's back to normal.. for a while. I can also restart the Apple TV and it's also fine - for a while. It eventually re-pairs.
Any way to prevent this?
