[Guide] Intel IGPU HDMI/DP audio (all Sandy Bridge -> Kaby Lake [and likely later])

RehabMan said:
Wrong. IOPCIPrimaryMatch must be native ID. RM,device-id should be set to the id you want to spoof.

So your native id is 0x1a70, so IOPCIPrimaryMatch should be 0x1a708086.
And RM,device-id you want to fake as 0x9d70, so should be <70 9d 00 00>.

oh! :)

ok, i have amended that one but still the same issue, no hdmi output in sound preferences

i have attached also the plist from the hdmi audio kext just to make sure i have done it correct as well! :)

I had a typo previously...
Your Info.plist is wrong. You have IOPCIPrimaryMatch=0x1a708086, should be 0xa1708086 (to match your native id).
And that is why you don't find FakePCIID under HDEF in ioreg.

oh wow! it works! amazing! thank you so much! you're awesome! :)

Did you check in Windows yet to determine what device DP is connected to?
Seems like an obvious place to start.

Why are you injecting "hda-gfx" and "layout-id" on B0D4? (that is complete nonsense).
Click to expand...
Actually I'm not thouroughly understanding the fact behind this hack, so just try and fail. With only hda-gfx injecter on IGPU, I have only hda-gfx under IGPU in ioreg. But you stated that it works only when there existed under both IGPU and HDEF, so added one more for B0D4, from the the fact that it's B0D4 instead of B0D3 on my machine.
By the way, what steps should I do on windows to inspect the display port issue. Googled for a while, but no help.

B0D4 is not related to this topic.
B0D3 (renamed HDAU) is used on Haswell/Broadwell.
It is not used on Sandy/Ivy/Skylake/Kaby Lake.

Just because the name of something is close (B0D3 vs. B0D4) does not make it related. ACPI identifiers are only 4 characters, so there isn't a lot of room for creativity.

Look at display properties with a monitor plugged into it. What graphics device is it using?

Interesting thing that we must sometimes reverse these two... I'll put out an update to FakePCIID that has it reversed for both. Then people can decide if they need it.

Was the PublishHDMI_DP thing also needed or does it not matter at all?

that would be good for others if they need it. i have left the publishhdmi_dp thingy in there for the moment, i will remove it tomorrow and test and will let you know :)

ha! i don't need the PublishHDMI_DP thing! just tried without it and all still works great! :) thanks again for your time and effort in helping me getting this working :)

BTW, I put out a build of FakePCIID that has the changes.
Please test.

have tested, installed both FakePCIID.kext and FakePCIId_Intel_HDMI_audio.kext and all works as expected! thanks again! :)
