No HDMI audio on hd4600 z97

I managed to get onboard audio, except through HDMI. When i checked in Hackintool "Intel Haswell HDMI" it says that I need to spoof Audio ID (which is 8086:0c0c /PCI0@0/HDAU@3 = PciRoot(0x0)/Pci(0x3,0x0) ). Yet I don't know how to spoof Audio id in opencore and to which value i am suppose to spoof. I tried installing FakePCIID and FakePCIID_Intel_HDMI_Audio kexts but without any effect. I am only using Whatevergreen + AppleALC kexts . Do I need to spoof audio id, install additional kexts or do I need to patch somehow framebuffer? Thanks.
