Audio - HDMI Audio AppleHDA [Guide]

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.

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.

Confirm you have a bootable backup.
Brute force is required and may not work
SSDT-HDMI-NVIDIA-PEG0-2.aml did not work, remove
Install edited SSDT2.aml attached
Add the property shown to config.plist and install

I finally find a way to inject my graphics card property, and it's working now!:lol:
I use EFI string to inject "hda-gfx" property in config.plist and your SSDT to inject HDAU device now, HDMI/DisplayPort are all working now.

But I'm still confused, why graphics DSDT and SSDT patch/injection will cause glitch/blackscreen/kernel panic, are there any difference between my DSDT and SSDT to others'?

Really appreciate your help!
