Audio - HDMI Audio AppleHDA [Guide]

Sound works but no HDMI sound option.

HDMI device is on a DP framebuffer connector, edit required.

Two choices (install one method, verify, revert before installing second method):

1. Try 0x01006601 Framebuffer:
Edit dsdt/GFX0/AAPL,ig-platform-id
Find:
0x03, 0x00, 0x66, 0x01
Replace
0x01, 0x00, 0x66, 0x01
Save and restart.

2. Edit Framebuffer 0x03006601:
AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri
Find:
0x03006601
Find:
020500000004000007040000
Replace:
020500000008000006000000
Save, install and restart

This did it! Thanks a lot for the help, my hack is now officially complete, I'll document the process for future reference

PS: For the record I edited the dsdt, but instead of GFX0 I edited IGPU as I patched that. After rebooting with the HDMI connected, resulted in half the screen of blurred video, so I was not able to validate if audio worked or not.

Hey Toleda,

So i upgraded to 10.11 public beta latest update and i have my evga 960 working well as far as displays are concerned but my hdmi audio doesn't work. it doesnt even show up.

I am running clover latest revision and i did the applehda patches using your command tool (which ps- i love when i used to use my 580. great great tool!) but i still have nothing.

Weird thing is, right now i have inject nvidia = false for clover but when i make it true, i get my display port to hdmi audio device show up but i lose multi-monitor.

Am i doing something wrong?

I have a ga-ex58-ud5 (Bios version 13)
i7 920
GTX 960

I tried the auto patch command tool for el capitan and that didn't work (although it did detect my other sound drivers which it wasn't doing before).

I also have a patched DSDT from when i needed help with the GTX 580 i used to use.

I am attaching all the files as requested

I would really appreciate some help View attachment Jimmy's Mac Pro.zip

No connector-type injection, dsdt edits or ssdt required. See Post #1.

Maybe im just really lost because im pretty sure i did those edits. I changed the numbers from 0x00010000 to 3

then i copied that over to my efi directory under acpi/patched.

I'm probably (Definitely) missing something.. :// i can see my regular devices, but i just dont see my hdmi audio out like i used to.

That edit is for onboard audio with HD3000/HD4000 HDMI audio, restore the original value.
2nd request, see Post #1.

Just restored to original and i lost all my sound devices :// Sorry for the trouble i honestly don't know what else to do. When i had the gtx580 changing the number to 3 made my hdmi work so i figured i could do the same thing since the only thing that i changed was my gpu.

Don't know why it's not working.View attachment DSDT.aml

Attached is the DSDT that i am now using.

No dsdt/HDMI audio edits, see Post #1.
For onboard audio, edit dsdt/HDEF/layout-id:
find
0x75, 0x03, 0x00, 0x00
replace
0x01, 0x00, 0x00, 0x00

Here's the edited dsdt and a picture of what i have enabled for my sound devices - still no hdmi audio. The sound devices didnt show up after the dsdt edit- i had to run the audio_clover_alc_110.command file to get them and patch my applehda and insert the values in clover's config.View attachment DSDT.aml

still no hdmi audio.

For the 4th time, no HDMI audio dsdt edits results in no HDMI audio.
See post #1, edit you dsdt for HDMI audio.
