ALC 255 - Microphone not getting detected

[EliteMacx86]

Yes, it's recognized as a headphone.

Okay and i guess no input.

Check with the supported Layout IDs on AppleALC page. Provide the tests report.

I was kinda expecting this. Remove AppleALC and use InsanelyDeepak ALC255 AppleHDA. Make sure you backup your original AppleHDA first.

Backup? I only have Apple ALC's kext. Not Apple HDA.

Please note that AppleHDA is must. Doesn't matters, if you use AppleALC. AppleALC works in conjunction with AppleHDA. It's stored in S/L/E.

Oh. Okay. I thought that it's a kext which needs to be stored in Opencore's kexts folder.

How can I install this in Opencore? It requires Clover and CloverHDA.
Also, it is supported till Mojave 10.14. Whereas, I have 10.15 Catalina.
