[solved] HDMI audio issue on HD520

[Jeevu]

Hey community,

I am unable to get HDMI audio working on my hack. I have tried all the patches for patching connector type from 04 to 08 for port 0105.

I am using ig-platform-id: 0x193b0005 as it has 4 ports by default. My HDMI device connects at FrameBuffer@1 being port 0105.

I also tried manually patching the binary inside AppleIntelSKLGraphicsFramebuffer but I am still getting connector type 04 in IOREG.

I have tried booting with invalid platform id and without caches. I have rebuilt caches many a times but still it is not working.

hda-gfx is being injected on HDEF and IGPU (No HDAU as it is SKL). FakePCIID is also attaching to HDEF (EDIT: Removed as I think it is not needed in my case)

Note: I am using AppleALC for audio and hence I have set "UseIntelHDMI" to true in my config.plist.

To sum it all up: The connector type for port 0105 stay 04 no matter what! Clover kext patch didn't change that. Manual Editing didn't change that. Weird but true. -_-

What did I miss? I have attached a debug report from @black.dragon74 script.

The ioreg you attached shows no HDMI monitor connected.

Note: Native 0105 data in 0x193b0005 is <01050900 00040000 C7010000>, not <01050900 00040000 87010000>

Noted. Fixed. I thought the rest of data would be same. Silly me.
Thanks.
