Apple’s latest HomePod and Mac betas contain more references to a four-speaker home theater system. The findings strengthen evidence that Apple is developing a larger wireless surround setup for Apple TV 4K, but the company has not announced it.
Code researcher pdfu found new surround-system logic in HomePod 27.2 beta 3, including a diagnostic that associates a speaker with a particular surround group. Separately, Aaron Perris identified new four-speaker symbols in macOS 27.2 beta 3.
The discoveries follow earlier tests in which tvOS 27.2 beta could connect two pairs of HomePods to an Apple TV 4K. MacObserver’s earlier report on the beta feature noted that the software was unfinished and did not establish final hardware support.

What remains unknown
Apple currently documents support for one HomePod or a stereo pair as the default Apple TV audio output. A true four-speaker layout would add separate front and rear positions, but beta testing has not yet confirmed how consistently those roles work across movies, music, menus and games.
Compatibility is another open question. Earlier code referenced four second-generation HomePods as well as a mixed arrangement involving unreleased speaker hardware. That does not prove current HomePod mini models or every Apple TV 4K generation will support the finished feature.
Apple was already testing four-HomePod processing in earlier software. Beta 3 adds another layer of evidence, but buyers should wait for Apple’s release notes and support documentation before purchasing extra speakers for this setup.
The feature could still be delayed or limited before release because code and symbols show development work, not a public commitment from Apple.
