What is your receiver?[/QUOTE]
It's a Denon X3200W, a 2015 model. But the DTS version updated about a month ago. Since then DTS-HDHR, and only DTS-HDHR, does not work anymore.
How do you connect it to PC, via HDMI or Optical?
HDMI of course, DTS-HDMA / DTS-HDHR is not possible via Optical.
Please go to Settings>Audio, please be sure to set audio passthrough and tick all the sub-options to try again.
Passthrough options are set.
If still have problem, please post Player 5 log files and a screenshot of the audio settings window.
I won't show my private logs in public, can I mail them to you?
Here is the screenshot:
