Thanks @RehabMan .
I am not able to get HDMI audio on my TV.
- I get HDMI audio sporadically with my current settings and (PR files attached.) only when I boot with the HDMI cable connected to the TV. If I hotplug, there is no HDMI audio.
- If I lose HDMI audio, even after booting with the cable connected, I make some random changes in the framebuffer-con1* values (enable and disable the keys) and finally restore it exactly back to where I started from. This exercise sometimes restores the HDMI audio, if I boot with the cable connected again, but definitely not if I hotplug.
- The connector type for AppleIntelFrameBuffer@1 does not change to 00 08 00 00 and it's stuck at 00 04 00 00 regardless of the cable is connected or not. Also, there is no HDMI shown in System Preferences>Sound>Output even though I am able to get the video output on the TV.
One more thing is that there used to be a pink tint on the TV, which I worked around by using the "patch-edid.rb" script. I never faced this in High Sierra.
I have tried other SMBIOS models also, such as the MacBook Pro 14,1 and 14,2.
HDMI audio works in Windows. Also previously it worked using the "0x591b0000, 0105 instead of 0204, HDMI" patch, in "KextsToPatch".
PR files generated after booting with HDMI cable connected, otherwise it wont show in IORegistryExplorer.
It is a typical problem with KBL.
You might experiment with different ig-platform-id values, different framebuffer patching, and FakePCIID_Intel_HDMI_Audio.kext.
