Wireless sound synchronization function appeared in 2019 – allows you to use the iPhone microphone to configure the sound more accurately. However, he did not support Dolby Atmos through AirPlay and Bluetooth, so users had problems with sound and images.
Now these problems can be solved. After the update, you need to go to Apple TV in “Settings”> “Video and Sound”> “Synchronization of Wireless Sound” and watch the instructions on the screen.
