Forget HomePod 2, all AirPlay speakers could soon get full Apple TV 4K support

It looks as if Apple has been devising a way to allow any AirPlay 2 speaker to act as your default Apple TV 4K sound solution – at least, that's suggested by code found in the first beta of iOS 16.1, which was released to developers last week. 

Right now, both of Apple's HomePods (the original and the newer HomePod Mini) can be set as default speakers for Apple TV 4K, meaning that everything you play from your Apple TV automatically comes through them (though only the discontinued original HomePod can deliver Dolby Atmos audio).
