How to get GA-Z97-HD3's audio to work with High Sierra?

After upgrading to High Sierra I find that those kexts installed in /Library/Extentions no longer work (probably cuz my primary drive is a SSD under APFS). So I copy and paste them into /Volumes/EFI/EFI/CLOVER/kexts/Other including, for example, RealtekRTL8111.kext for Internet (of which works), and realtekALC.kext for the audio (of which does not seem to be working). This is probably because besides installing RealtekALC.kext in /Library/Extensions, multibeast also adds codec-specific patches for AppleHDA.kext into /Volumes/EFI/EFI/CLOVER/config.plist and adds codec specific zlib files into /System/Library/Extensions/AppleHDA.kext/Contents/Resources. This might not be compatible with realtekALC.kext in /Volumes/EFI/EFI/CLOVER/kexts/Other.
