macOS/HDMI audio is configured correctly
What adapter?
Try the other mDP connectors
Ive attached a pic of the adapter I'm using. No luck on changing to other mDP. I tried all 4 and no dice. The sound does work out of the motherboard when I plug in speakers to it. But still no HDMI sound. Ive also attached a screenshot of my sound options from when I changed ports.. When I had the GTX 745 it showed my monitor as a sound option.

Agree, macOS/Nvidia HDMI audio is enabled.
Thanks. I'll just make due with the audio from the motherboard. At least I do get that when I plug in Speakers back there. Is DP audio and HDMI audio the same? I wonder if I get a true DP monitor and plug in without the use of an adapter will it work.

Hello again,

I do not have sound but do have the audio choices including HDMI audio from monitor. Im sure I am missing something simple.

Sierra 12.6
Asus Z170I Pro Gaming
Intel i3-6320
GTX 745
Used audio_cloverHDMI-120.command.zip

Thank you.

[Edit] I have solved the issue. The problem was my BIOS settings. I have both onboard audio and HDMI audio. I have deleted the ioReg file. Thank you.

I'm on High Sierra.
I've been trying to get the HDMI sound out of my GTX 760 with your guides but nothing seems to work.
I have a X99 Gaming 5P motherboard with integrated CA0132 audio chipset.
I don't have a DSDT because I don't really need one. Everything works perfectly on my Hackintosh expect for the sound.

The script audio_cloverHDMI-130_v0.5.command simply outputs:
EFI partition is mounted
Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem
Continue without HDEF/onboard audio (y/n): y
No audio codec detected

and dies.

I've tried to follow the instructions from here:
https://github.com/toleda/audio_hdmi_amd-nvidia/tree/master/ssdt_hdmi-nvidia

I've installed attached SSDT-HDMI-NVIDIA-BR3A with the appropriate changes for X99 , but still no sound.

I've also attached by IOReg.

Thank you!

Problem, macOS uses only HDEF, not ALZA. Fix: Install ssdt_hdef-1-x99-alza.zip

Fail. Remove and install the unedited version
