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

[Cr1ms0n]

Attach ioreg without the HDMI device plugged in.
You should also test without FakePCIID_Intel_HDMI_Audio.kext. Not all hardware requires it.

@RehabMan,

YOU ARE A LEGEND!

Removing FakePCIID_Intel_HDMI_Audio.kext did the trick!! Not sure why I was convinced it was required. Both sound and picture working perfectly on both laptop and TV. (TV needed an extra EDID override for forced RGB mode in order to get a full resolution without pink/purple tone, but that was an easy fix).

Thanks again RehabMan!

ig-platform-id 0x0a260006 does not have the 0306 connector.
If your hardware uses it, you will need to add it or use an ig-platform-id that already has the 0306 connector.

Look at my github repo... for example there is some 0306 Haswell related patches in the ProBook github.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something

You did not patch the framebuffer connector-type for HDMI <00 08 00 00>. It still shows DP <00 04 00 00>.
The patch you need for 0105 HDMI is disabled in your config.plist.

Quick question, on my laptop the hdmi port outputs through the nvidia 1050 discreet card when in windows, in macos nothing at all as its disabled. I haven't looked into the hdmi too much due to the 1050 outputting through the hdmi in windows. Do you think Im right in not having hope.
