Very odd, thanks for the message about that, I think the MSI is using redirect rather than true form factor, I can see the missing form factor for headphones (doesn't say anything at the bottom).
I will have to look into this, although I cannot promise anything since I dont have an MSI with headphone redirect, which as you said in your message its Nahmic?
As a side note, most issues are with MSI, even in the past.

Some thoughts, not sure how this works yet, but I remember the Nahmic mirroring device, which I guess is for headphones. It counts as a virtual device.
It will probably need programming like it was a USB device, however the missing form factor means APO4 wont know what it is.
It might be possible to add a form factor via registry, depending on the device, else you would flick it (
see here).
Note: If you try to change SPDIF-HDMI to the Speakers form factor, even if it worked, you would lose bitstreaming.
Its possible for DTS to program the service to recognize SPDIF-HDMI as 'External-Speakers', like APO3.*
* PCM is PCM.

Personally I suggest Gigabyte or Asus, however no brand is immune to mistakes. Main stream chips, ideally not a USB version.
Also note a good GPU will also count as a dedicated sound card, although with no APO's or software.
Currently I am running my AMD over my Realtek, Realtek-DTS APO's, Interactive 5.1 to Z906.

Here are the EPO settings I am using with DTS DCH and with SFX "Any" "Any" (5.1) in the preset, if I was recording from SFX, I would set the upmixer LFE and balance to 0:

Balance effects all PCM audio, multichannel or not, the upmixer will only apply when 2 channel (stereo) is played, not more.
To override webrowsers, which like Interactive output a finite number of channels (6), set 0 to 6.
Remember to set it back after, else 6 channel audio will be upmixed left-right.

If you followed post 1 fully (including pnputil), and still cant get Interactive to show on SPDIF-HDMI, try
this policy first (not for USB), then ask.

Taking a short break, nothing to update (not likely to be improved much), dont worry I am still here for feedback and questions.
