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

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.

Don't patch conX-flags. Remove FakePCIID_Intel_HDMI_Audio.kext.

As a general rule, you apply patches only as needed.

Hello RahabMan,
I am new to Hackintosh , I always liked your work and started the project.
My system is custom barebone mini pc with I7-8550U - UHD620 with 1- miniDP and 1 HDMI ports, Audio - ALC269 , I tried your plists like hd620 and NUC i7 ... from their respective threads and guides. I followed your laptop guide using clover as my system specs are related to laptop hardware / intel NUCi7 hardware. I have done a clean install (vanilla) using your guides. Everything seems working , but HDMI audio is not working, Audio on MiniDP is only working if hot plugged( disconnecting and reconnecting after booting to desktop. Audio port is working _ ALC269 with AppleALC.kext and audio platform id-17 injected. Can you please help with HDMI audio. Attaching CLOVER.zip

No HDMI audio codec detected. Make sure it works in Windows (eg. enabled in BIOS, etc).
Then experiment with different RM,device-id values (using FakePCIID_Intel_HDMI_Audio.kext).

"Problem Reporting" files are incomplete.
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.

Thanks for your reply, I am attaching the problem reporting files.

You are not injecting any properties to patch the connector-type for the HDMI connector.
Read post #1.

Hello Rehabman
I followed the guide as it is .... and I had patched my MiniDP and HDMI both.
-Audio on both the devices work but only if hot-plugged.
-I have to disconnect and reconnect the cable after booting for the audio to work.
-And I cant swap between MiniDP and HDMI after booting with any one of the port (if I boot with HDMI port I can’t swith to MiniDP port and vice versa) I have to restart the system if I want to switch between HDMI and MiniDP

Just want to know if this is normal... if not do you want to me to post the current problem reporting files. Thanks for your help....

Problems when you are not hotplugging are typical.
