IOS 11.3 and tvOS 11.3 will support AirPlay 2 (interspace playback)
earlier today, Apple released beta versions of iOS 11.3, tvOS 11.3 and macOS 10.13.4. Now some users have found that iOS 11.3 and tvOS 11.3 have finally ushered in AirPlay 2 support, which means playback 2 every other space. The new compartment 2 allows you to command your home's sound system and speakers flexibly.
you can play a song in the living room and kitchen at the same time, adjust the volume in each room, or play your music instantly on all speakers. When the iOS device is upgraded to iOS 11.3 and one or more fourth-generation / fifth-generation Apple TV upgrades to tvOS 11.3, we can use interspace playback 2 to play music synchronously on multiple devices.
after installing tvOS 11.3, you are also prompted to add Apple TV to the HomeKit settings, and you can select a room during the setup process. After the configuration is completed, the Apple TV will be displayed in the home app, and currently only supports playing and pausing music.
in the current beta version of iOS 11.3 and tvOS 11.3, the function of interspace playback 2 is still very limited, and the player can only support Apple TV. In the future, however, both third-party speakers and Apple's own HomePod will support alternate playback 2, when users can really use iPhone to control speakers in multiple rooms to achieve a multi-room audio playback experience.
