I am back and am now using an Active DP to HDMI adaptor on the GTX 1070. Still no audio over HDMI.

Attached are all the logs, files and screenshots requested.

Steps: After finding out HDMI audio was not going to work without a DP adaptor I removed the HDMI Audio SSDT from my system.

Got DP Adaptor, made sure it worked in windows then booted into OSX and ran the 120 command with the EFI mounted. It said everything was good and to reboot. Still not option for HDMI audio under SysPrefs / Sound.

Thank you again for the help.

Sierra 10.12.4 Latest Nvida Web driver.

Why?
Enables both HDMI audio and DP audio.

Because I did not know any better.

But, I only removed it until the Display Port to HDMI adaptor came, but I went through the process again and it successfully detected, downloaded, and placed the SSDT into ACPI/Patched. So it is back in there now. But yeah, I just wanted to make sure everything was done like it was the first time.


So that is what i did.

Ah, now I see why you asked that. i sent the wrong "patched" folder. Here it is

Note: The ioreg and everything else I included in my original zip was taken when the system booted with SSDT-HDMI-NVIDIA-PEG0.aml in patched.
