1. Description of audio problem
I am attempting to enable HDMI audio by way of using a DSDT loaded using Clover. Loading the DSDT has no effect as to enabling / giving access to hdmi audio.
2. OS X version/motherboard model/BIOS version/processor/graphics
OS X 10.10, GA-Z97N-Gaming 5, BIOS version F3 (note: this is the latest version of the BIOS for this board, version F4 is for the Z97N/HZ97N WIFI motherboards.),
Intel(R) Core(TM) i5-4690S CPU @ 3.20GHz, Intel HD Graphics 4600, 16 GB 1600 MHz DDR3 RAM.
3. Procedure/Guide Used
[Guide]_HD4600-hdmi_audio_(dsdt_or_ssdt)_v2.pdf
Run MaciASL, open its preferences, click on "sources" and add:
https://raw.github.com/toleda/audio_hdmi_9series/master .
Close preferences and click on "Patch", after patches load, click on “AMI-Clean_Compile-9Series", then click on “Apply”. Close Patch dialog.
Click on “compile”. It compiles and gives one warning about using a reserved variable name: ”12184, 1099, Unknown reserved name (_HRV)”
Click on "Patch" again and this time select “AMI-HD4600-AMD-Nvidia-A1”, click on “Apply”. Close Patch dialog,
Click on Compile. After compiling (the same warning about the unknown reserved name appears)
“Save as..." DSDT.aml ("ACPI Machine Language Binary")
Copy the file to EFI/Clover/ACPI/Patched/DSDT.aml
Reboot.
Check Sound Preferences control panel, but only the standard sound out devices appear in the Output subsection.

6. System/Library/Extensions/AppleHDA.kext
Note: this is the stock kext Apple supplies with Yosemite (AppleHDA 266.5, Copyright © 2000-2014 Apple Inc. All rights reserved.).
7. System/Library/extensions/AppleHDAxxx.kext (if installed)
Note: AppleHDA1150.kext (AppleHDA1150 v3.1.0, Copyright © 2013-2014 Pike R. Alpha. All rights reserved.), this is the kext that is created by the Pike R. Alpha method of enabling ALC1150 audio. Installed via the guide:
http://www.tonymacx86.com/audio/143757-audio-realtek-alc-applehda-guide.html . There was no major reason to pick this version over the other available versions, it works as well as extracting the ALC1150 package from the MultiBeast 7.0 software and installing that. I had tried some of the other listed methods to see if they gave HDMI audio access, but thus far I only have only been able to enable basic 2 channel audio.
Note: This motherboard does not have different colored audio input/output jacks, all are the same black color, there are three rows, two columns.
Note: No Framebuffer edits have been done, however:
Using the hdmi cable ===> AppleIntelFramebuffer@1 with display0: port-number, Number, 0x6
Using the DVI cable ===> AppleIntelFramebuffer@0 with display0: port-number, Number, 0x5
Using the DP cable ===> AppleIntelFramebuffer@2 with display0: port-number, Number, 0x0

Note: This ssdt is used to generate CPU P-States and CPU C-States. I used Stork’s guide. Built under Yosemite rather than copying the old one from Mavericks.
