This problem was diagnosed through multiple steps over at fanedit.org: https://forums.fanedit.org/showthread.php?tid=16140

It turned out the the WAV files produced by Premiere were resulting in a broken DTS file, despite the fact that (a) nothing could detect anything wrong with the WAV files and (b) DTS’ own tools verified the dtshd file. (It was just every other decoder that identified the DTS file as broken.) Very weird.

For the reference of anyone finding this thread in the future having the same problem, here’s the “solution”:

  • Creating an Audacity project file with all the tracks.
  • Doing a Gain adjustment across all tracks.
  • Exporting as new WAV files.
  • Encoding a DTS file using the new WAV files.

The resulting DTS file has no volume/gain loss and is no longer “broken”. My best guess is that making the Gain adjustment forced Audacity to re-encode the file in a way that (a) conversion didn’t and (b) eliminated whatever element was causing the DTS suite to glitch out. But since there’s no clear reason why Premiere would be exporting a buggy WAV file, none of the tools I’ve used have been able to detect anything wrong with the WAV file, and DTS’ own tools don’t detect anything wrong with the dtshd files that all other decodes consider broken, that’s just a wlid guess at this point.

But if it works, it works.
