you put the kext in clover kext folder or in Library/Extensions. make sure all audio kexts are original and untouched. in clover patches or in DSDT you try the layout id's for your codec on the list.

i downloaded prebuilt binary AppleALC.kext and install in S/L and install Un-patched AppleHDA.kext(using KextBeast) S/L/E but it hasn't detect my Laptop Audio.

i also tried to install AppleALC.kext in EFI/Clover/Kext/10.11 it hasn't work either.

 

or i have to create AppleALC kext using Xcode for my Codec.

according your link my only Modification regarding Sound is i m injecting layout id -3 in my DSDT apart for this i don't do any modification regarding Audio 

in DSDT or Config.plist.
