Audio - HDMI Audio AppleHDA [Guide]

[mrkpeek]

Green: Expected
SPDIF: If green works, SPDIF works, details?
DP: Details
HDMI: HDMI audio does not work on the HDMI port, Nvidia problem.

IOReg: shows GFX0@0 and PEG0/GFX1@0 instead of PEG0/GFX0@0, how and why?
IOReg: what display is connected to what port?

Tkx for the quick response!

DP: No sound
Green: Ok then, this is no biggie
SPDIF: since you mentioned it should work I decided to test my cable. Cable is not working properly. I don't have another to test it so, it should be it.
HDMI: didn't know...i lost so much time trying...

IOReg / GFX0@0 and PEG0/GFX1@0: to be honest, I have no clue. How do I fix it?
IOReg / Displays: I just have one monitor so I have DP and HDMI are both connected to my Predator X34. Just for tests. I’m planning to connect HDMI to my Home Theater.

I hope I answered your answers correctly (I’m a newbie on this is stuff).

Thank you!

have no clue. How do I fix it?

It is not in the dsdt or attached ssdts, Have to remove something, don't know what is doing it.
Did not answer if IOReg shows HDMI connector or DP connector.
Attach IOReg using DP connector.
Once DP works, a DP2HDMI adapter will provide HDMI audio

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?

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.

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?

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

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.

Nothing to do with audio.

can't control the volume for DP

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.
