Hi Toleda,
Have been running 10.11.6 for along time with one of your old ssdt's to enable Nvidia HDMI (via DP) audio on my rig.
Today i Updated to 10.13.5 ... have everything working except Nvidia HDMI Audio.
I carefully read through Posts #1 & #2 .... Implemented HDMI audio via SSDT-HDMI-NVIDIA-PEG0.aml downloaded from your git repo and applied the 10.13.5 work around from post #2 ... (option 2 - Clover AppleHDAController patch) but no luck with getting any HDMI audio on my LG Ultrawide Display.
I also tried running your CloverHDMI script ... it downloaded the same SSDT that i manually downloaded but still does not work.
Note: It made a backup of my Clover config.plist but as far as i could tell made no changes ?
System Info:-
Running MacOS High Sierra Version 10.13.5 with latest Nvidia Web Driver 387.10.10.10.35.106
Motherboard is ASRock Z97 Extreme 6 With the latest BIOS
CPU is Intel I7-4790K / 16 GB RAM
GPU is Nvida 980 TI connected to LG Ultrawide 34" monitor via DP 1.2 cable
Like i said all was working fine with my previous OSX 10.11.6 install so i know that the hardware and cable are good.
I tried some of the other methods from post #1 such as lilu/NvidiaFixup but still no audio so went back to your method/ssdt.
Have checked and rechecked that the work around patch i made is correct for my GPU (device=id = b0 0f 00 00)
My Clover patch looks like this :-

Would really appreciate any help on this issue ... requested debug files in attached zip file.
Many thanks for all you do for the community.
