Change cobba ic,then use eeprom tools3.1. If still don't work check components near audio ic.

open service manual, lokk for c120, replace it.
I f not solving ur problem, check path from microphone path to c102, then check or replace cobba.

play it with handfree first , to make sure, MAD and COBBA is ok !
if "XMIC" by handfree working , then.

you check :Vcobba at V101 ok ? and L402 !
