Hi I have the latest Apple TV 4K and just bought and set up the HomePod Mini. The Apple TV was setup in the home app as “living room”. Setup the HomePod and it’s in the same room. Problem is I can’t change the default audio from the Apple TV to play on the HomePod. When I go to default audio device, it just shows my Samsung TV as an option. Both running latest OS and both work fine. How do I do it?
