Lip Sync Apple Tv. Some have found success disabling the match av settings. Using the same connection with a roku 3 i don’t experience any of this.
This happens after less than 20 minutes of viewing; I'm using it on my pc, so there's no app as far as i'm aware and i can't find a framerate setting. Upon pressing play the tv will wait to begin playback for the 2 seconds, and then start video perfectly in sync with the audio stream, and pressing pause the audio will continue for 2 seconds past the video then pause.
If it still fails, contact apple support.
Switched back to the old apple tv and everything is fine. This happens after less than 20 minutes of viewing; Some have found success disabling the match av settings. Hi i see lip sync issues when using the plex media server, and i see it on all my connected devices.
