Audio - HDMI Audio AppleHDA [Guide]

[GuyShellmarr]

Ok, I retrieved everything I could. See below and attached. Thanks for looking at this!

1. HDMI Audio not showing up in Sound Preferences.

2. 10.12.1, Gigabyte Z170X-UD5-TH, Bios Ver. F5, Skylake i7-6700k, EVGA Nvidia GTX 950

3. Used Multibeast, ALC1150 selected, manually added AppleHDA.kext to system/library/extensions, manually added HDMIAudio.kext to /EFI/Clover/Kexts/Other/, used your script to add SSDT-HDMI-NVIDIA-PEG0.ami to EFI/CLOVER/ACPI/Patched/

4. See attached (IOJONES File)

5. See attached

6. See attached.

7. NA

8. See attached (do not have debug.log, or dsdt.aml… only .aml file in the patched directors is SSDT-HDMI-NVIDIA-PEG0.aml).

Unsupported/Non-working Realtek ALC AppleHDA

1. 100 Series

3. ssdt injection (select one ssdt)​

x16 versus x8, no difference??

I mean I haven't tried swapping the card's slots. Should I?

 

[toleda]

haven't tried swapping

Bought 28 lanes only to use 12? Your choice.

Bought 28 lanes only to use 12? Your choice.

But how do I get HDMI audio working. I ended up with that many lanes due to my cpu. Also it doesn't really make a speed difference or so it seems

 

[toleda]

it doesn't really make a speed difference

macOS does not support SLI, one graphics card installed; relevance?
See Post #1891.

Did you just move graphics cards and that was it? What did you do afterwords?
