Apple has released tvOS 18.5. The most important new feature concerns audio playback: The update now enables Dolby Atmos syncing across AirPlay and Bluetooth speakers. Apple TV users who use wireless speakers can finally resolve a known issue.
In recent years, there have been repeated complaints that the audio—especially with Dolby Atmos—was not synchronized with the picture when speakers were connected via AirPlay or Bluetooth. This was particularly noticeable in dialogue: lip movements didn't match what was being said, and sound effects like explosions were delayed. Until now, the only solution was to switch to 5.1 surround sound—a step backward for anyone who had invested in high-quality Dolby Atmos-enabled speaker systems. With tvOS 18.5, Apple is now responding to this feedback.
What exactly changes with tvOS 18.5
The new update introduces a feature that allows Dolby Atmos to be correctly synchronized across wireless speakers. Whether you connect your speakers via AirPlay or Bluetooth, the new feature ensures that the picture and sound are synchronized. Apple calls this feature "Wireless Audio Sync." It's designed to help compensate for the latency between Apple TV and external speakers. This makes Dolby Atmos playback significantly more precise and natural—a noticeable difference, especially in films and series with lots of effects or fast-paced dialogue.
Where can you find the new feature
You can find the new setting at:
- Settings > Video and Audio > Wireless Audio Sync
There you can start the sync. Apple TV analyzes the latency between the device and the speakers and adjusts the audio output accordingly. This works with HomePods as well as other speakers connected via AirPlay or Bluetooth.
Why is the update important
Many users have long reported issues with Dolby Atmos over wireless connections in forums like Reddit or in Apple's own support discussions . The complaints ranged from slight offsets to significantly disruptive asynchronicities in sound and picture. This was particularly frustrating for many with HomePods, which officially support Dolby Atmos. The new feature in tvOS 18.5 should represent a real improvement for these users.
