I have done hours of research and not found out a answer to this. My brother and I play split screen on Call of Duty Ghosts and we both have Bose Headsets with microphones on them. We try to play things like extinction where you want to have a lot of people talking to communicate. We are unable to tell if our mics are working though. We assume that they are not because when we talk, the little mic does not show up and sometimes, the mic symbol will appear in the corner. It will flash for a few seconds and disappear. I really want to know if this is a glitch, or if it was made purposely. Thanks for all of the help.
