Confirm you have a bootable backup.
Brute force is required and may not work
SSDT-HDMI-NVIDIA-PEG0-2.aml did not work, remove
Install edited SSDT2.aml attached
Add the property shown to config.plist and install

I finally find a way to inject my graphics card property, and it's working now!:lol:
I use EFI string to inject "hda-gfx" property in config.plist and your SSDT to inject HDAU device now, HDMI/DisplayPort are all working now.

But I'm still confused, why graphics DSDT and SSDT patch/injection will cause glitch/blackscreen/kernel panic, are there any difference between my DSDT and SSDT to others'?

Really appreciate your help!

Try other DP ports.


Yikes, I only have 1.

Is it possible the adaptor is at fault? It is active and then I just found this this buried in the product info.

"Apple transmits audio over DisplayPort/Thunderbolt in a unique way. Implementing support for this feature on Apple systems would have resulted in the adapter no longer qualifying for VESA (DisplayPort) certification."

Is it possible this applies to hackintoshes using your SSDT as well?


Is there an active DP > HDMI you'd recommend?

Thanks

Script incorrectly determined Nvidia HDMI audio is enabled.
Install ssdt_hdmi-nvidia-PEG0.zip to EFI/CLOVER/ACPI/patched/
Restart and reply with new files.

Thank you Toleda. I manually installed the aml from the zip file and rebooted. Still no additional audio devices showing in sound output. Have tried all 3 DP ports. Attaching files as requested. Thanks again.

ssdt is working. DP audio device not recognized. Different problem, no suggestions.


Dang, looks like we both need to break out those 3.5mm 1/8" patch cables unto a new Nvidia driver comes along.
