This happened awhile back with PMS, but was eventually fixed as far as I know. I noticed today that my DTS-HD tracks will not show as available and only show the core. I tried to search around and surprised no one else had mentioned it. Is this potentially something I can fix on my end?

Your screen shots clearly show that the DTS-HD MA audio has been recognized by Plex.
In the bottom screenshot, that is the only DTS track Plex sees. You can see it is 1536 kpbs only (the core track). That being said, it still sees the profile as “ma”.
Also in the first screen shot “AUDIO English (DTS 7.1)” should say “DTS-HD”. The logo is the only thing that is correct.
Lastly, when in actual use, Plex only plays the core track.
I’ve attached the full XML from PMS and the MediaInfo for this file. Just to be clear, this is an issue with my entire library, not just this one file and it only is an example.

If this is a problem with your entire library can you provide some more details on your playback device: hardware, OS, Plex player version?

Thats normal. It has never shown DTS-HD for me but works just fine bitstreamed–for me.

Sure,
Windows 10
PMS 1.3.2.3112
Plex Media Player 1.2.0
Is there anything else I can provide that would help?
I’ve tried to re-analyze various movies with no luck. Nothing has changed with my server with regards to hardware since the problem started.

You are bitsteaming or decoding with PMP?
If I understand you correctly, I have tried both. I don’t think I can tell which track is playing when PMP is decoding since it’s all PCM. (I may be misunderstanding your question here).
That being said, I think this is an issue stemming from PMP, not the player. PMP isn’t even advertising the MA file as being available. This happened in a previous version of PMP before as well.
I see your issue. I crosschecked some of your older postings and see you have a Sony AVR capable of HD Audio decoding. I am assuming you want it to do the work. I also remember answering a previous question of yours about the difference between DTS-HD MA vs FLAC:
Since you only checked passthrough for Dolby Digital (AC3) and DTS (DCA), thats all that will be sent to your AVR for decoding. You must check the three other selections: Dolby Digital Plus (EAC3), DTS-HD Master Audio and Dolby TrueHD in order to send those bitstreams to your AVR for decoding. Since you configured PMP to passthrough DTS, that is what its doing–sending just the DTS core.
Excerpt from your config:
“passthrough.ac3”: true,
“passthrough.dts”: true,
“passthrough.dts-hd”: falsetrue,
“passthrough.eac3”: falsetrue,
“passthrough.truehd”: falsetrue
The config needs to be set to true for those last three.
If I turn on the setting in PMP, when DTS-HD is selected, the receiver receives PCM audio. So, Plex is handling the decoding itself in this example. I am unable to tell what the receiver is receiving since Plex is decoding it. When the check box is selected, PMP should be sending the bitstream of DTS-HD to the receiver (which Plex actually recommends not to do).
But even if this did solve the problem, Plex Media Server only sees the Core track. In the XML, in the Info settings, and on the Movie profile, it only shows the Core track. The only evidence of the actual DTS-HD Master Audio within Plex Media Server is the logo. That’s it. I think the issue stems from the source, which is PMS.
Your XML and MediaInfo is the same as mine. Your screenshots are gone now. DTS Core is only 5.1. Your screenshots showed 7.1 which would be either DTS-HD High Res or DTS-HA Master Audio. I don’t think it is your source. Did you turn on exclusive mode as well? How many channels of PCM do you see right now?
Do make sure you have the latest Intel Graphics drivers installed. HD Audio bit streaming does not work with generic High Definiton Audio Device under Windows. It needs to be the Intel Display Audio Driver which comes with the Intel Graphics Drivers.
