Earlier today, Apple released the first beta of iOS 11.3 and tvOS 11.3. While tvOS 11.3 does not bring much to the table, iOS 11.3 does contain a number of new features and enhancements. The point release of both OS’s also adds support for AirPlay 2 that allows for multi-room music playback.
This means that if you own multiple Apple TVs — only the fourth and fifth-generation Apple TVs support AirPlay 2 — in your home, you can stream the same music to them at the same time.
Apple had first announced AirPlay 2 at WWDC 2017 when it had unveiled iOS 11. However, the feature will be making its way to the OS only when iOS 11.3 and tvOS 11.3 are released to the public in spring this year.
When you first update your Apple TV to tvOS 11.3, you will be prompted to add the device to your HomeKit setup by adding it to a room. After this, your Apple TV will be displayed as an available device in the Home app of your iPhone. Right now, you can only use AirPlay 2 to stream the same music to multiple Apple TV units in your home and not much. However, given that Apple still has a couple of months before the final release of iOS 11.3 and tvOS 11.3 drops, the company is likely going to make improvements in this regard and add more functionality to it.
Apple’s HomePod will have gain support for AirPlay 2 with a future software update. This would allow iPhone owners to stream the same song to multiple HomePod speakers in their home at the same time. Additionally, Apple will also be making AirPlay 2 available for third-party speakers and hardware makers for integration in their products and services.[Via MacRumors]
