Use patched AppleHDA (or AppleHDA injector), not AppleALC.kext.
Read FAQ:
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/

Note: Currently, I don't even know how audio is working with your setup. You have no patched AppleHDA components installed, and AppleALC.kext should not even be loading due to FakeSMC.kext being installed and InjectKexts=Detect.

Yes! its works, My mistake was to use AppleALC.kext, but, Realtek audio working fine with AppleALC.kext installed in /EFI/Clover/kexts/Other, when I deleted AppleALC.kext Realtek audio lost.
Im install generated with Mirones patch aDummyHDA to S/L/E and "Kernel and kexts patches" in Clover and live vanila AppleHDA.kext, now Realtek and Intel HD working fine!
Thank you!
USB porst works fine to, but I'll try Guide USB power property injection for Sierra

Hi RehabMan, I have some problems... hope you can help me.
I tried to make my own patch as there isn't one for HD530 and it seems to be working, in fact IOReg shows me 00 08 00 00 but after I connect the HDMI cable it goes back to 00 04 00 00 and stay that way even after I disconnect the cable. I think I did everything you said in your awesome guide.

I searched my ig-platform in AppleIntelSKLGraphicsFramebuffer with an HEX editor and I found this code, which should be the one referring to the AppleIntelFrameBuffer@2(the one my HDMI port use): 02040A00 00040000 87010000. So I made a patch that replace this code with 02040A00 00080000 87010000. As I said it works as long as I don't connect the cable. After that, it goes back to DP and HDMI audio doesn't work.
Maybe there's something wrong with the others things that are in the guide.
Thanks in advance!

I have a odd problem. I have two HDMI ports, without "FakePCIID_Intel_HDMI_Audio.kext" installed, one port can output audio, but after I installed "FakePCIID_Intel_HDMI_Audio.kext", both ports don't have audio any more.

Use ig-platform-id 0x191b0000.

FakePCIID_Intel_HDMI_Audio.kext is used "as needed." It is not for all hardware. Trial/error is the name of the game.

Is it possible for both of my HDMI ports to have audio?
