No Audio Devices - AppleHDA Realtek Audio

Hi, I have Clevo P650SE and working on Hackintosh Mojave. But never had audio since installation. I have no alc-layout-id field in IORegistryExplorer. debug zip is attached.

Thanks in advance!

So I did the latest Security update on Sierra (10.12.6) and now my sound doesn't work anymore.
My motherboard is the Gigabyte Z77-DS3H with an ALC887 sound card.
What I already did, is reinstall the ALC887 driver with MultiBeast - didn't work. Then I installed ALC887 legacy driver with MultiBeast - didn't work. Finally I installed VoodooHDA - doesn't work either, just says ERROR in Preferences Pane. No output devices shown in settings.

Mac OS 10.12.6
Motherboard: Gigabyte Z77-DS3H - Bios Version F11a
CPU: Intel i7 3770k
GPU: Nvidia GT640

Thank you for the help

Full stop. Installing other audio options ensure audio recovery, impossible.
Then I installed ALC887 legacy driver with MultiBeast - didn't work.
Not applicable to your motherboard, waste of time
Finally I installed VoodooHDA - doesn't work either,
VoodooHDA conflicts with AppleHDA, bad idea
Missing, 4. Copy of IOReg; attach
 
Thanks for your help in diagnosing my problem.

1. Description of problem:
I have had a working and stable hack for 4 years now. Audio has never been a problem. I have always simply ran multi beast with ALC 898, restarted and it just worked.

Out of no where, my audio devices have disappeared. I am not sure how this happened, there were no discernible changes to my system that I could find.

2.
-OS 10.13.6 Motherboard:
-Gigabyte GA-Z87X-UD7 TH (series 8)
-bios versio f2
-i7-4771
-GTX 970 (nvidia web drivers)

3. Procedure/ Guide Used - I followed this guide: https://www.tonymacx86.com/threads/applehda-realtek-audio-guide.234732/#post-1606764

This happened two days and so I followed the guide, which I did not understand at first but after careful reading, installed the OS High Sierra over my existing installation and then ran Multi beast and my audio devices came back.

This morning however, I turned my computer on and my audio devices had disappeared again. I ran the installer again and ran multi beast but it did not work this time. I am not sure what to do now.

Notes:
-Nothing happened when I ran: ioreg -rxn IOHDACodecDevice | grep VendorID

Questions/ things I don’t fully understand:

-Since Mac Os natively supports 898 on on Series 8 motherboards, do I need Apple ALC?
-Should I have a copy of Apple HDA and Apple HDA in my Clover/kexts/other folder?
-Do I need Apple HDA and ALC in both S/L/E as well as Library/ Extensions?

Thanks again for your help!

I guess I have overlooked this step :)

No audio codec, BIOS update?
Since Mac Os natively supports 898 on on Series 8 motherboard
Not true, the only native codec is proprietary Cirrus Logic 4206 and newer.
do I need Apple ALC?
Mojave and newer, yes. See AppleHDA Realtek Audio/Post #1/I. and II.
-Should I have a copy of Apple HDA and Apple HDA in my Clover/kexts/other folder?
-Do I need Apple HDA and ALC in both S/L/E as well as Library/ Extensions?
Never, do not touch AppleHDA
No audio when no audio codec
