tvOS 18.5 Adds Synchronized Dolby Atmos Playback for AirPlay and Bluetooth Speakers

The tvOS 18.5 update that Apple released yesterday adds support for synchronizing Dolby Atmos playback to speakers over AirPlay or Bluetooth, according to Apple's release notes for the update.

Apple TV 2022 Feature Blue
The feature could help address some persistent syncing issue that some Apple TV users have encountered when trying to play audio with Dolby Atmos. There are multiple complaints on Reddit and the Apple Support forums about Dolby Atmos audio syncing issues with sound bars and speakers, including those connected via ‌AirPlay‌ and Bluetooth, such as the HomePod.

On affected devices, users find that dialog and other audio can be slightly out of sync with the content that's playing, so lips do not move correctly when people speak in TV shows and movies, and sound effects like explosions are delayed. Switching to 5.1 surround sound eliminates the problem, but people with expensive audio setups have been understandably disappointed not to be able to use Dolby Atmos.

Apple says that the new Dolby Atmos synchronization feature for ‌AirPlay‌ and Bluetooth speakers can be found by going to Settings > Video and Audio > Wireless Audio Sync.

I just recommend watching the Apple TV with AirPods Max. Headtracked spatial is the future on so many dimensions.
Works only if there's no more than 1 person watching, does it? And then you have to wear those headphones, e.g. can't lie sideways, have to keep them charged or on a cable when bingewatching, get warm ears,... .

Personally, that headtracking where the sound is then tracked to the position of the screen, distracts me. I switch that to fixed position.

Can confirm that the WAS utility has been completely revamped and now it first plays a stereo PCM tone followed by a Dolby Atmos tone.

Also it now works as it should, completely eliminating lip sync and audio lags issues from AirPods Pro, Max and HomePods.

Not only that, but now, if you do the sync in say, 4K SDR 60hz, it compensates and calculates the difference automatically for the rest of the frame rates, so you only need to do it once.

Great little update.

EDIT: For the new version of the tool to work correctly, the IOS device used to perform the calibration must be on 18.5 as well. If not, the Atmos tone wont play and the utility wont compensate the delay for the rest of the frame rates.

I wonder if this will allow using HomePod mini as rear or side satellite speakers.

How about proper syncing just for multiple HomePods? I have about 15 in the house and can barely get two to play in sync, much less several across rooms. This has never been awesome, but actually got worse with the new Home version "upgrade" last year.
