Dolby Atmos sync issue with Apple TV
Whenever I play Dolby Atmos content, there is a delay in audio playback in relation to the video. Dialog is slightly out of sync from lips. Explosions are heard slightly after you seem them. The delay is about 1/6 of a second.
Hardware used: Apple TV 4K, Samsung Series 7 TV, and Vizio Elevate Soundbar.
I tested in both configurations and had the same results:
- Apple TV 4K connected to Samsung Series 7 TV's HDMI 2 input. Vizio Elevate Soundbar connected to HDMI eARC.
- Apple TV 4K connected to Vizio Elevate's HDMI 2 input. izio Elevate Soundbar connected to HDMI eARC.
The issue only happens when view Dolby Atmos content. If I set the Apple TV to only output in 5.1 surround, the delay disappears.
I play with the AV delay of both the TV and the soundbar and was not able to sync the audio and video. The lowest setting on the AV sync is the closest I can get the audio to the video. Increasing the setting makes it worse.
Below are the list of apps with varying results:
Disney+ Noticeable audio delay with Dolby Atmos content. Disabling Atmos fixes the sync issue.
MAX Same as Disney+
Netflix Same as Disney+
Paramount + Noticeable audio delay with ALL content.
Additionally, I also tested the Samsung TV's native Netflix app since it is the only one that outputs Atmos through the eARC. No sync issues with the TV's native Netflix app when playing Atmos content.
Is there a solution for these syncing issues when playing Atmos content on the Apple TV?
