tvOS 27.2
Juli Clover (release notes, security, developer):
Today’s update adds support for four-speaker surround sound, a feature that works with the HomePod, HomePod mini 2, and the upcoming Apple TV 4K.
It allows the Apple TV 4K to be used with four HomePod mini 2 speakers, four second-generation HomePods, or two HomePods and two HomePod mini 2 speakers to get surround sound.
