It seems that there is a problem such as not being able to play Dolby Atmos format audio on Apple TV.
It is said that this bug has not been resolved even with the latest tvOS 15.4.1.
Dolby Atmos becomes silent, choppy, out of sync with images
This bug occurs when playing videos with Dolby Atmos format audio on Apple TV 4K.
- The voice becomes silent
- Misalignment occurs without synchronizing with the image
- Audio is choppy
It is that such a phenomenon occurs.
Apple’s support forums haven’t been followed by users reporting similar symptoms since a post about this bug in September 2021, and the thread already has 26 pages.
According to reports, this bug seems to occur mainly when watching videos with Dolby Atmos format audio in the Netflix app, but some users have also reported that other apps have also had the problem.
The only way to avoid the problem is to turn off Dolby Atmos.
This bug is not resolved by installing tvOS 15.4.1, the latest OS for Apple TV 4K.
You can play the audio without problems by disabling Dolby Atmos in the settings, but Dolby Atmos creates a more immersive experience, so early action is awaited.
Dolby Atmos is the audio format that Apple has adopted for Apple Music as “spatial audio,” and is supported by many Apple products.
