The new fourth-generation Apple TV 4K, announced last week, can connect to up to four HomePods in front-left, front-right, rear-left, and rear-right positions, enabling an all-Apple surround sound system for home theater setups. A related feature that has received less attention is Whole Room Audio.
Apple says Whole Room Audio spreads sound evenly across four HomePod speakers in a room. "Whole Room Audio spreads sound evenly across four HomePod speakers for audio that's perfect for parties or game day," Apple says. "Everything from music to sports commentary comes through clearly, no matter where you are in the room."
According to user "pdfu," who has been examining Apple's software code, Surround Sound and Whole Room Audio will be separate speaker mode options in tvOS 27.2 when four HomePods are connected. Surround Sound offers controls such as Spatialize Stereo and a Surround Level adjustment of −8 dB to +8 dB for the rear pair. Whole Room Audio has no audio options, as it assigns the left channel diagonally to front-left and rear-right, and the right channel to front-right and rear-left. When enabled, this gives a more consistent stereo experience regardless of where listeners stand or face. Apple notes the feature is ideal for parties, where people may not always be facing the TV. Rumors had previously referred to it as "Party Mode."
Four new HomePod mini 2 speakers can be used with the Apple TV 4K, or users can mix pairs of HomePod mini 2 and full-sized HomePod 2 speakers, as long as the front and rear pairs match. Previous-generation Apple TV 4K models remain limited to two HomePods for stereo sound.
The new Apple TV 4K launches Friday, November 13, and the HomePod mini 2 launches Friday, October 30. Both can be pre-ordered now.
