PLEX audio dropouts and sync issues with seamless branching on 4K TrueHD/Atmos movies

Just FYI I also added another new issue which may be related (I don’t know - but seems to be high-bitrate or Dolby Vision files) I have noticed a lot lately which makes watching 4K Bluray rips pretty horrible to watch on PLEX/Shield - constant freezing of entire movie for a random number of frames and/or skipping of frames entirely - so entire movie stutters/stops and/or things in movie instantly teleport to another position eg the car at end of the example clip I added to linked ticket youtube clip. It completely takes me out of movie every time it happens. Some people said they did not notice it while watching, but I could see it every time - in the recorded example clip the video froze for 10 frames in the first glitch. Posting here as the new ticket seems to have been ignored.
