I have an issue with Audio sync with only the channels app after I enable Wireless Audio Sync under video and audio on the Apple TV. When Wireless Sync is enabled other apps don't experience the audio sync delay. I enabled this so my apple air pods the audio will be in sync when I use them with my Apple TV. The audio sync delay occurs with channel when using both my sound bar and air pods. If I disable Wireless Audio Sync the problem goes away with my sound bar with channels. I then have a slight audio sync delay when using AirPods. My AppleTV is on IOS 14.2. I don't know if this occurred in old release as I just started using my AirPods with my Apple TV.
Has anyone else had this issue?
