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.

To fix go here

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

Fixed my issue!
