Video playback freezes or audio silences at certain parts with ATV 4K

With the ATV 4K, I have remuxes that pauses (w/ FLAC) or mutes (w/ PCM) near the end at the same timestamp (different per video) when the lossless audio track is selected. This issue cannot be found with the official Plex app.

Common features with both videos:

  • MKV container with 1 video track, 2 audio tracks, and at least 1 subtitle track.
  • 1st audio track is EAC3.
  • 2nd audio track is lossless (FLAC/PCM), 24-bit, and 2-channel.
  • Track IDs are not in order.

I can share both videos.

Issue is still present with the latest update.
