Hello @toleda !

1. Description of HDMI audio problem

I'm experiencing no HDMI audio while connecting my GTX 1060 through HDMI to my Samsung TV.
It does not list the Samsung HDTV on the Sound Devices.

2. OS X version/motherboard model/BIOS version/processor/graphics

OS X Version: macOS Sierra 10.12.5
Motherboard: MSI Z270 TOMAHAWK
BIOS Version: 7A68v12
Processor: Intel Core i5-7600 @ 3,5GHz
Graphics: EVGA GeForce GTX 1060 6GB

3. Procedure/Guide Used

Audio - HDMI Audio AppleHDA [Guide] - https://www.tonymacx86.com/threads/audio-hdmi-audio-applehda-guide.143760/

Here are the specific steps followed:

1. Downloaded the audio_cloverHDMI-120.command.zip
2. Mounted EFI with Clover Configurator
3. My SIP is disabled (CsrActiveConfig = 0x67, is that a problem?)
4. I have only one HDMI display connected to GTX 1060
5. Executed the audio_cloverHDMI script
6. Restart

Everything else is attached.

I read on this thread that NVIDIA Web Drivers does not support audio over HDMI, only through DP. Is this the problem?
Should I buy a DP to HDMI adapter as I also read or have I any other way to solve this?

Thank you very much for your time and help to all of us.

Is this the problem?

Yes.

Should I buy a DP to HDMI adapter

Yes.
HDMI audio ssdt is working, HDMI port is not.

 

[tembra]

Yes.

Yes.
HDMI audio ssdt is working, HDMI port is not.

So SIP needs to be ENABLED to install HDMI audio ssdt? Very weird while everything needs SIP to be disabled haha.

Once I get it working I'll see SAMSUNG HDTV as a sound device, but audio will not work because of HDMI port, that's it? Or I'll ever see the sound device because of HDMI port issue?

Thank you.

Hello Toleda.

I couldn't fix my HDMI audio on my laptop. I tried to patch my config.plist with your patcher and method with SSDT edit, but it didn't help. Help me please.

My hardware is describe below. ACPI tables, config.plist, list of kexts and IOreg dump are attached.

So SIP needs to be ENABLED to install HDMI audio ssdt

Not true; Post #1 says: SIP enabled, OK

Not using any Post #1 methods, why post to this thread?
IOIReg is useless, connect HDMI device.

Sorry, I thought that you can help me with laptop. If it is so, I attached IOReg with connected HDMI.

 

[toleda]

hought that you can help me with laptop

Only support Post #1 methods.
IOReg shows Port 0x5 patched, remove.
Install appropriate patch for Port 0x6.
