Ive Included all informative information I could think of.

Replaced the SSDTs because they got replaced with the scripts I tried apparently, still no DP Audio with these.

This can be solved with a driver or is new hardware required?

For most Pascal, it is a driver problem.

IOReg does not see a HDMI audio codec for the display attached.
What display?

Actually I just turned on my Mac, change the kabel one more time to the 1st DP and I got an audio.

Thanks again @toleda

I think I may return my mini 1070 from Gigabyte and grab the new MSI one that recently came out.
