ALC 255 - Microphone not getting detected

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.

Layout 15 - Headphone Distortion, No Internal Speakers, Internal Mic OK, Line in with nothing detected
Layout 17 - Good Audio output but low volume, Headphone OK, Speakers OK, Internal Mic OK, No External Mic
Layout 18 - No port detection, Speakers OK, Internal Mic OK
Layout 21 - Nothing works
Layout 27 - Better Audio output, Headphone OK, Speakers OK, Input - Line in and Internal Mic detected but both of them do not work.
Layout 28 - Good Audio Output, Headphone OK, Speakers OK, Internal Mic, No External Mic
Layout 30 - Good Audio Output, Headphone OK, Speakers OK, No External Mic, Line In detected but doesn’t work

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.
