Default Fix for No Audio during calls

At some point flashing roms I lost Audio during phone calls. I could not hear anyone on a call and they could not hear me. I think my modem was flashed when I flashed the international G2 MiUi rom.

Download to modem file extract it and flash the file with Odin (select the modem file in the phone section of Odin).
