Code discovered within audioOS 27 beta 8 for the second-generation HomePod reveals references to a four-speaker surround sound configuration, new audio calibrations, and a "Party Mode." Forum user pdfu identified tuning files specifying front and rear left/right speaker positions. Front units handle standard audio, while rear units provide omnidirectional sound, system notifications, and Siri responses. The setup includes dialogue processing, bass management, and dynamic range control for movies and multi-channel content. Spatial audio synchronization adjusts based on user settings. Party Mode aims to distribute audio ambiently rather than focusing on a single listening point. Although these features are present in the current beta, they reference an unreleased model, potentially the HomePod mini expected in 2026. Consequently, the surround sound capabilities may not launch with the initial audioOS 27 release. The code paths are publicly verifiable, confirming the existence of these advanced audio processing instructions within the operating system's private frameworks.
