AppleHDA HDMI Audio [Guide]

Does that mean Windows passes HDMI audio through the dGPU Geforce? (because it works under Windows)

Yes, unless Nvidia graphics is disabled; no HDMI audio.

GA-Z97N-WiFi, i7-4790K

I did a clean install of Mojave 10.14.1. I used Multibeast 10.4.0 for post install (image below). Everything seems good. I don't use wifi or bluetooth. The card that came with the motherboard was removed. I have audio using the green audio jack on the back panel with "Internal Speakers" selected in sound output. I just don't have hdmi audio as an output option. From previous MacOS installs, I used a script by Toleda that enabled hdmi audio for me. It was "audio_cloverHDMI-130_v0.8". I assume that method is no longer desired.



I assume I need to follow A. AMD/Nvidia/Intel - acidanthera/WhateverGreen since B. Intel - RehabMan/FakePCIID - is listed for laptops.

Lilu and WhateverGreen kexts were already added during the MultiBeast post install. I am confused on how to do the Framebuffer edits in method "A" under "Intel". Also, do I need to undo my current working alc892 audio from the MultiBeast post install before doing method "A"?

Attached are the problem reporting files.

Thank you

MultiBeast 10.4/Audio (all selections) does not support Mojave, supports High Sierra only.
892: see Mojave AppleHDA Audio. Remove MultiBeast method, install latest kexts. Off topic.

Nvidia HDMI audio ssdt is working
macOS does not see Nvidia HDMI audio codec, verify BIOS enabled

After my Post Install using MultiBeast 10.4.0 in post #896 above, I performed the below steps to undo MultiBeast audio kexts and get a clean install of audio for Mojave (based on @toleda's recommendations in post #898 and post #1). I now have working HDMI audio in addition to the audio ports on the back of the motherboard.

Remove

• AppleALC v1.3.0 was in L/E
• realtekALC v2.0-toledaALC-130 was in L/E
• Lilu v1.2.5 was in L/E
• AppleHDA v282.10 was in S/L/E (modified by Multibeast Audio Install)

Remove 3 AppleHDA patches from config.plist under ‘Kernel and Kext Patches’ using Clover Configurator

———————

To enable onboard audio in Mojave (clean audio install method), perform the following:

Add

• AppleHDA v282.10 (native) in S/L/E with KextBeast
• Lilu v1.2.8 and AppleALC v1.3.3 in EFI/CLOVER/kexts/Other (drag and drop)

Used audio inject under devices in config.plist layout ‘1’

• Realtek - ALC892 - 0x100302, layout 1, 2, 3, (4 for laptop), 5, 7, 12, 28, 31, 92, 98, 99

———————

To enable HDMI audio in Mojave, perform the following:

Remove

• WhateverGreen v1.2.0 was in L/E

Add

• WhateverGreen v1.2.4 in L/E with KextBeast
• Lilu v1.2.8 in L/E with KextBeast (now duplicated in EFI/CLOVER/kexts/Other and L/E; similar to FakeSMC)

I used the title "config(HDMIaudio).plist" while making the FrameBuffer edits. I later renamed it "config.plist" and overwrote the config.plist file in the EFI folder.

Thanks to @toleda and the many others that contribute to our audio installs

Problem Reporting:

I've been unable to get HDMI audio through my hackintosh. When I try updating my current version of Lilu along with its plugins (WhateverGreen and AppleALC), my system goes into a boot loop until I change the kexts back to their original old ones. I am at a loss for how to get HDMI audio.

OS: High Sierra 10.13.6.
Motherboard: Dell XPS 8910
BIOS Version: 1.1.6.
Processor: Intel i7 6700
Graphics: NVIDA GTX 750 Ti (Will be upgrading to a NVIDIA GTX 1070 TI soon)

Method/ Guide Used: A. AMD/Nvidia/Intel - acidanthera/WhateverGreen (in addition to the NVIDA section of instructions)

I was able to install AppleALC.kext but now I have no audio through my ports anymore nor HDMI port. Also when installing updated versions of Lilu and WhateverGreen, my system will not boot up. The versions used are attached. I have downloaded the latest versions of each from the links provided along with AppleALC. I have posted the uptaed kexts used below
