Apple TV tvOS 18.5 Update Enables Dolby Atmos Wireless Audio Sync

Apple has released the tvOS 18.5 update for Apple TV, introducing a significant enhancement to its Wireless Audio Sync feature. This update focuses on improving the synchronization of Dolby Atmos surround sound audio with video playback, addressing a common issue where audio and video can fall out of sync in home theater setups.

Originally introduced in 2019, the Wireless Audio Sync feature uses the iPhone’s microphone to calibrate audio output from the Apple TV to connected speakers. The new update extends this capability to Dolby Atmos audio, allowing the system to automatically adjust for latency issues when streaming audio over AirPlay or Bluetooth connections.

Users who have experienced out-of-sync audio with Atmos-enabled soundbars and speakers can now use this tool to recalibrate their setup. The calibration process is accessible via the Apple TV settings menu under Settings > Video and Audio > Wireless Audio Sync, where users follow guided steps to synchronize their audio and video perfectly.

This update addresses widespread user feedback reported on forums such as Reddit and Apple’s community discussions, where many complained about persistent Dolby Atmos audio lag issues. By leveraging the iPhone’s microphone for precise calibration, Apple aims to deliver a seamless home theater experience with accurate audio-video synchronization.
