This method doesn't work for my board. I've tried the two of them (see below), numerous times.

Rog Rampage VI Extreme is ALC1220
[NONE OF THE METHODS WORK] There are two methods:
# NOT WORKING: EITHER NO AUDIO or DEVICES DONT APPEAR IN SETTINGS
[Doesn't work] -- 1. Patch Apple HDA
# DOESNT WORK, DEVICES ARE IN SETTINGS BUT NO AUDIO
But basically it's only these steps:
- Set in clover Audio ID to 1 in the injection field (if you don't know it's ok, the audio_cloverALC-130.sh will do it)
- execute audio_cloverALC-130.sh
- Answer yes to all questions but make sure the choosen audio ID is 1
The script will place the kext patches automatically in your Clover configuration.
WARNING: THE SCRIPT WILL ALSO PLACE A realtekALC.kext IN YOUR 10.13 FOLDER OF CLOVER KEXTS!!!!!! MAKE SURE TO REMOVE IT IF YOU UNINSTALL THIS METHOD
[Doesn't work] -- 2. Don't patch Apple (make sure it's not patched) and use AppleALC.kext
# NO AUDIO DEVICES APPEAR IN SETTINGS
No matter what, no devices appear in the OSX settings panel
Regarding VoodooHDA
VoodooHDA works but crashes. Probably because of HDMI. Try to run Valley.app with sound, it should crash after a few seconds. Now run it without sound, it should work just fine.
