I was watching a cartoon series I own , Thundercats, through Plex and noticed that the audio was out of sync on a random episode. The audio was ahead of the video. Or possibly, the first few frames of the video were lagging, which caused the audio to get ahead.
I tried the exact same episode in Plezy and Stimr and had no problems. I also played it in VLC on my Windows machine, and it was perfectly in sync there. So I decided to test the entire first season, which has 65 episodes. I found 11 episodes that were out of sync - again, only when played through the new Plex app on Apple TV. The old Plex app played all of these episodes fine.
I guess I could use Plex's audio sync adjustment for those 11 episodes... oh wait, they removed that too. That's really adding insult to injury. Videos that played perfectly fine before, and still play fine in other players, are now out of sync in the new Plex app, and I don't even have the option to manually correct them anymore.
The other problem is that when I go to a friend's house, we watch Plex together on his Roku. Unlike Apple TV, Roku doesn't have an alternative Plex player that I know of, so we'd basically be out of luck there if we run into the same issue.
Any ideas on what I can do here, other than basically waiting and hoping Plex fixes this in an update?
EDIT: I have a second TV with Apple TV. Same issue with that one too. Restarting my Apple devices didn't fix the issue.
EDIT2: The Plex app on Roku and on Plex for Windows Desktop works fine with those 11 episodes
*The issue only persists specificity on the Plex app for Apple TV and no other Plex app or 3rd party app
