You mean the rear thunderbolt port? Well it's a real pain. I have no solution beside the super dangerous firmware flash, which I wouldn't recommend unless you are very confident with it.
What ASRock implemented on this motherboard is this:
I have no TH devices, a shitty usb type C adapter, so...
Big Sur 11.2.3
Please remember to:
insert your Mac address in Config.plist\Platforminfo\Generic\ROM
customize your own serial number with GenSMBIOS.command
change OC\Kexts\USB.kext\Contents\info.plist\IOKitPersonalities\Macmini8,1-XHC\IOProviderMergeProperties\ports as per your...
Sorry I forgot to mention that: SIP was already disabled (btw, how come you use csr-active-config=E7030000? I believe we need to set it to FF0F0000 and add NVRAM -> Delete -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> csr-active-config as stated here)
Also, I don't have any active patch in ACPI...
Even though I would prefer AppleALC as the most brilliant solution to me so far, I tried VoodooHDA-OC.
No joy, here.
Here are the steps
Deleted Device Property injection
Implemented SSDT for HDEF, hda-gfx=onboard-1, GFX0 to IGPU, AAPL,ig-platform-id, HECI to IMEI since there is...
ResetLogoStatus is set to YES cause I have a custom boot logo. I'm pretty sure (I can be wrong) that Boot Graphics Resource Table has nothing to do with my HDMI issue.
The AAPL,ig-platform-id I'm using is the result of many trial/error steps. You can use at least two of the many that...

I'm trying to bypass Whatevergreen, and it's quite easy: I have onboard IGPU, onboard Audio, HDMI Audio (with the above unplug/plug problem) via SSDT injection (attached).
I can't manage the frame buffer patching via Kext patch in open core/config.plist
No AppleHDAHDMI_DPDriver shows up in your IORegs. Perhaps your monitor doesn't have audio. Thank you anyway.
One last question: I noticed in your config that you're using layout-id 11 for your on board Audio. Any particular reason?
@bertaz You mean as soon as you boot the system with a connected display on iGPU you have Digital Audio from that display without unplug and replug it back?
What bios version are you on?
In fact, would you do a small test for me, please?
Power off the system
Attach to onboard DP or HDMI a...
Great! It happens I have right now on my hands the same motherboard. No dGPU. Everything works fine with the sole exception of UHD 630 HDMI Audio. It works only after unplug/replug the monito (both on HDMI and DisplayPort port). Would you please test it for me and report here on my thread...
