Audio - HDMI Audio AppleHDA [Guide]

[biscate]

Hello again Toleda, sorry for my late contact, it was carnival in Brazil last week ;-)

Desktop Only

Sorry if I am off-topic. This guide has useful information for me.

No HDMI device attached in IOReg.
Unusual ssdt configuration
See Post #1/[Guide] Gigabyte BRIX using Clover UEFI (GB-BXi5H-4200/GB-BXi5-4570R/GB-BXi7-4770R)
In the linked repo, see Gigabyte-BRIX-s-DSDT-Patch/config.plist
Add:
ACPI/DSDT/Patches/change B0D3 to HDAU
Devices/Arbitrary/Intel HDA
Devices/Arbitrary/Intel HDMI HDA

In sequence of my first post #992, as described in your guidances (post #993), added to config.plist (using PLISTEdit Pro):

ACPI/
DSDT/
Patches: change B0D3 to HDAU (exactly copy of original Gigabyte Brix one)

Devices/
Arbitrary/
Intel HDA (used same Gigabyte Brix PCIAddr=00:1B.00 / Changed Layout ID=3)
Intel HDMI HDA (changed original Gigabyte Brix PCIAddr to 00:02.00, as shown on .IOReg/GFX0@2 / Kept Layout ID=1)

Still no HDMI device on Audio devices.
Also, lose RehabMan's Backlight patching (not shure if it is related with the recent config.plist edit).

I have attached my config.plist and io

Thank you again.

tried many methods, but I can not solve.

No files, no idea.
See Problem Reporting, Post #1. Attach all requested files.

AppleHDA only, remove Voodoo.

And after removing it?

Attach all requested files
IOReg, no HDMI device attached, attach new IOReg
dsdt/HDEF, HDMI audio edit missing

And after removing it?

Likely, no audio.
All Post #1 solutions require AppleHDA.kext enabled.

I see HDMI HDA in "config.plist/Devices/Arbitrary/1". Is it wrong?

Attach cloverHDMI script output

Not shure about what you're asking for.
I haven't ran any script to enable HDMI output, since I'm using a patched AppleHDA.kext (no script to install HDA/HDMI).
The config.plist file already lists HDMI patch on "KernelAndKextPatches/KextsToPatch".

Likely, no audio.

But I DO have an AppleHDA.kext in S/L/E. How do I "enable" it?

Yes.
Misunderstood the .rtf attachment
Kext patches are not the same as ACPI patches. BTW, only one framebuffer patch is necessary.
