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

[RehabMan]

Now I dont have any HDMI device to test. Are there any diffrent way to test ?

No.
And if you have no HDMI device, then I guess you have no need to implement HDMI audio in the first place.

Apparently this doesn't work on my Dell if I have AppleALC enabled. AppleALC keeps on changing the layout-id to 7.
I wanted to change the layout id to 66 since I'm preparing for the transition to Mojave (it only supports layout 66 in ALC283)
kextd stalls whenever I try to plug in an HDMI device. On my last attempt, I changed it to layout-id 3, but to no avail.
And I'm out of things to try. Can anyone provide some help? Thanks a lot.

I enabled them all, and it works now. Thank you!

Not sure what you mean by "enabled them all". layout-id is a singular choice... can only use one of them.

I meant the patches in config.plist/ACPI/DSDT/Fixes.
It works well now, with layout-id set to 66.

You didn't patch connector-type for HDMI.
Refer to post #1.

Hi rehabman
I have patchconnector-type for HDMI
The connector-type for AppleIntelFramebuffer@2 is <00 04 00 00>. After patching, it change to <00 08 00 00>.
Before Install FakePCIID_Intel_HDMI_Audio.kext I got audio work but not with audio hdmi after Install FakePCIID_Intel_HDMI_Audio.kext I lost my audio
My attach have HDMI device connected.
