tvOS 27.2 Beta Adds HomePod Surround Sound

Apple's tvOS 27.2 beta 2 lets Apple TV 4K pair four HomePods wirelessly, two full-size and two minis, for surround sound. The feature is incomplete: speakers cannot be assigned rear roles, so front and rear play identical audio, and menu and game audio only comes through front speakers. It works with Atmos and surround video sources.
