Ok, so I am obsessed with playing halo 3 online. i use a headset too, and love talking to people. but after a few rounds a little chat bubble appears next to my name in the list of players that are on your team (there is usually the microphone symbol) and then the headset wouldnt work. im trying to figure out how to get the headset to work after the chat bubble icon pops up. ive tried re-plugging it in to my controller, turning it on and off. please help?
