Apple may be testing a larger role for HomePod in the living room. MacRumors reports that code found in audioOS 27 beta 8 describes a possible four HomePod surround system, including front-left, front-right, rear-left and rear-right positions. The same code reportedly refers to room calibration, speaker mapping and different processing for movies and music.

This is evidence of testing, not a feature that owners can activate today. Apple has not announced a four-HomePod mode, and the current Home app and Apple TV settings do not provide that configuration. The code was found in a beta and could be changed or removed before release, so the report should not be read as a product launch or a promise of a specific date.

The reported layout would be a significant step beyond Apple’s existing approach. Apple’s support documentation allows two matching HomePod speakers to form a stereo pair, with one unit handling the left channel and the other the right. Apple also supports a single HomePod or a stereo pair as home-theater audio for Apple TV 4K. A four-speaker system would add rear channels and require more precise room setup.

Calibration appears to be central to the experiment. The code reportedly includes speaker-position mapping, timing adjustments, bass management, equalization and dialogue enhancement. Those controls could help the system account for different room sizes and seating positions. They could also make setup more demanding, especially for people who move speakers or use a room with reflective surfaces and open doorways.

The software references a second feature called Party Mode. MacRumors says it is intended for stereo-paired HomePods and would spread audio more evenly across a room instead of optimizing playback for one listening position. That could be useful for gatherings, but it is separate from a true rear-channel theater layout. The wording in the beta code does not establish exactly how the feature would sound or which HomePod models would support it.

Another reference points to an unidentified AID12007 hardware family in a tuning system called Forklift. MacRumors says that identifier could be linked to future HomePod hardware, but its purpose is not known. It may describe a new HomePod mini, a third-generation full-size HomePod or another speaker. No final hardware design can be confirmed from a software identifier alone.

Apple’s current HomePod remains a capable but closed-room-audio product. The company promotes room sensing, computational audio, Spatial Audio and Dolby Atmos support on the second-generation model, while its support pages limit official stereo pairing to matching speakers. A four-HomePod system would make Apple’s ecosystem more attractive for home theater, but the price of four full-size units and the need for compatible software could be substantial. For now, Apple appears to be exploring the idea, and owners should wait for an official release before buying hardware for the rumored setup.
