Administrators Bronxteck Posted June 7, 2016 Administrators Share Posted June 7, 2016 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.

Sumit Posted June 8, 2016 Author Share Posted June 8, 2016 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.
