The ioreg shows no HDMI device plugged in.
No expectation of HDMI audio without an HDMI device connected.

...

If the monitor is plugged to HDMI, this ioreg shows that connector has the wrong connector-type.
The display is attached to framebuffer@1.
And that connector-type is DP <00 04 00 00>. It it is actually HDMI should be patched such that it is HDMI <00 08 00 00>.
Also, FakePCIID_Intel_HDMI_Audio.kext may or may not be needed. Must try both ways.

@1 was HDMI <00 08 00 00> in the ioreg from post #11.
What changed between #11 and #13?

I removed FakePCIID_Intel_HDMI_Audio.kext and used this patch :

Name: AppleIntelSKLGraphicsFramebuffer
Find: <01 05 09 00 00 04 00 00 87 01 00 00>
Replace: <01 05 09 00 00 08 00 00 87 01 00 00>

change connector-type from <00 04 00 00> to <00 08 00 00>

change ig-platform-id from 0x19160000 to 0x191b0000

Now HDMI audio is working perfectly

Now that you have SKL spoofing working, you can work on native KBL graphics...
You will need 10.12.6 or later for that.

Hello

Mind to show me how you change the connector type?
Which section in config file?
Or maybe could share your config.plist for my references?

Thx
