TryinG to get this working on the hack book but I'm somewhat stuck at this stage. HDMI audio works in two conditions - unplugging and replugging after boot or I have to use fakepciid.kext and fakepciidinjectHDMIaudio.kext (both kexts cause crash freeze on Monterey). How do I go about setting up the EFI perfectly to get this working? Any advice is appreciated. Attaching two screenshots as well (first one with one connector is audio not detected and second one is audio detected with Kabylake HDMI). How do I make this Kabylake HDMI permanent? EFI also attached.
