Apple’s tvOS 18.5 Update Fixes Dolby Atmos Sync Issues

Cupertino, California — Apple has released the tvOS 18.5 update for Apple TV HD and Apple TV 4K, addressing long-standing audio synchronization issues experienced by users with Dolby Atmos surround sound setups. The update was made available on May 12, 2025.
The new feature enhances the existing Wireless Audio Sync function, enabling users to calibrate Dolby Atmos audio playback on speakers connected via AirPlay or Bluetooth. This adjustment aims to fix frustrating lags where the sound does not match the visuals on-screen, particularly when audio from dialogues and sound effects appears delayed.
Apple acknowledged these syncing complaints on forums, noting that many users had to revert to a 5.1 sound format to eliminate audio lag. The tvOS 18.5 update allows for audio calibration available under Settings > Video and Audio > Wireless Audio Sync. This streamlines the process, ensuring a more harmonious viewing experience without disconnecting speakers.
“We’re excited to offer this feature that addresses a common concern,” an Apple spokesperson stated. “It enhances the overall experience for those utilizing Dolby Atmos and ensures fans can enjoy movies and shows as intended.
Users are urged to update their devices to access this feature, which promises to eliminate previous frustrations for those who rely on Apple’s technology for home entertainment. As a result of this improvement, users looking to enjoy immersive sound with their Dolby Atmos setups can now do so without the worry of audio lag.
