Audio - HDMI Audio AppleHDA [Guide]

It is not in the dsdt or attached ssdts, Have to remove something, don't know what is doing it.

The only way I could make my GPU works with the right definition was installing the driver "emuvariableuefi" from Clove Configurator. Do you think it could have something to do with this?

Did not answer if IOReg shows HDMI connector or DP connector.
Attach IOReg using DP connector.

IOReg I sent was showing HDMI. Attached you will find IOReg using DP connector.

No, attached IOReg shows GFX0 as expected. Something changed between the capture of the two IORegs.

Attached you will find IOReg using DP connector.

DP audio is working. For HDMI audio, use a DP2HDMI adapter.

The only thing I did was uninstall the driver "emuvariableuefi" and install it back. Could that really be reason it changed?

That's great !!! I didn't noticed before, just after you mentioned it was working. Probably, it wasn't working because the PEG0/GFX1@0 issue...

I just noticed an issue. I can't control the volume for DP (Icons are faded). See attached screenshot.

Got it..."macOS does not provide HDMI/DP audio controls. No volume, no mute, no balance, etc. Use the connected DP/HDMI device (TV, receiver, etc.).

Well, it looks a I've all that is possible to work in place. Toleda, I truly appreciate your help! Thanks man!

I just would like to share that I learned about SoundFlower + SoundflowerBed to control volume on HDMI or DisplayPort Audio. It's working great for me on 10.12.6.
