1. I did a clean install of Mojave and DisplayPort audio was working originally but then stopped. Now only Headphones and Airplay shows up in audio output.
2. NUC6i5SYH
3. Used Rehabman guide for NUC with a clean install (not upgrade to High Sierra)
4-9. Attached

Thanks for the help.

Yes, the tool has no way to know what physical connector is.
Connect the display to each connector and make an IOReg.
Reply with 3 IORegs.

This is what I found. There are 3 ports: a HDMI 2.0, a HDMI 1.4 and a DP. For both HDMI 2.0 and DP, I got screen shots of IOReg and Hackintool attached. For HDMI 1.4, once it is in use, the system's boot up process hangs; I cannot even get it boot into safe mode. Looks like Port 5, 6, and 7 are HDMI 1.4, HDMI 2.0 and DP, respectively, right? What to do next? Thank you.

Nothing attached.
There is nothing more useless for problem solving than a screenshot of IOReg.

No Intel HDMI audio codec present:

ioreg -rxn IOHDACodecDevice | grep VendorID
 |   "IOHDACodecVendorID" = 0x10ec0283

Verify BIOS/.../Display audio/Enabled
Run Terminal command above
If no, 0x8086...., hardware problem
