AppleHDA HDMI Audio [Guide]

Would you mind checking this one out?

Looks better

still no HDMI sound output.

No attachments, not helpful.

Here.

Just to point out, I'm using FakeID in config.plist to make the graphics card work, with 0x67981002, which corresponds to an R9 280X/7970.
The "correct" ID would be 0x66131002 (Oland, R7 240/8550), but I couldn't get it to work. Maybe patching AMDFramebuffer?

(Thank you for the ongoing support!!)

Confirm you have a USB emergency boot drive
Edit config.plist/ACPI/DSDT/Fixes/
Set all to NO

0x3E7, I must have thought to disable System Integrity Protection completely, maybe to allow untrusted kexts? It's a parameter I don't recall changing myself, so there's that... as I said I've resumed working on this machine only recently.

Here's the output from Terminal:

I've been playing with those two ATI kexts, now I'm not using FakeID anymore, instead I've added the chip's real ID to the kexts' info.plist. I can revert and do it the other way if it's better anyway.

disable System Integrity Protection completely

0x67

allow untrusted kexts

0x3

sudo touch /System/Library/Extensions && sudo kextcache -u /

AppleHDA.kext should be signed
All non native kexts should be in L/E/

not using FakeID anymore, instead I've added the chip's real ID to the kexts' info.plist

Possible to go back to native AMD and FakeID?

Changed CSR to 0x3.

All the kexts listed in the terminal output are already in /L/E, except the ATI ones. I already restored the native ones (they don't show in the output now). AppleHDA, I restored extracting from the USB installer key (it's the one I attached on a previous post).

Now how should I go about making it signed?

(Side note-going back to FakeID and native kexts broke the framebuffer again, now I have a 7MB graphics adapter. Will tinker with it later..)

Answered, 1. run macOS installer or 2. Pacifist/macOS install dmg

That's what I did, although I extracted it from the USB stick I made with Unibeast. Maybe that's the issue? I'll try to redownload the installer itself and extract from there
