Optiplex 7060 opencore ALC255 Mic didn't work

Motherboard: Dell Optiplex 7060 MT
CPU: Intel Core i7 i7-8700 (coffee Lake)
GPU: Intel UHD 630
No mic at all
I tried
alc-layout-id (11-3-86-13-15-17-18-1-21-20-27-28-29-30-31-71-99-100)
all these layouts no mic worked with it, some layouts mapping Line in mic with internal noise.
