(adsbygoogle = window.adsbygoogle || []).push({}); I do not own an Xbox 360, but one of my friends does. He can talk to people in Xbox live parties, send/receive voice messages, and stuff like that, but when he goes to play COD4, everybody is muted, In the lobby and in game. He says that he has checked all parental controls and they are off (I haven't looked at that and don't know if its true, but assume it is). I personally haven't tried to help yet, but as I said I don't own a 360 and wouldn't be too much help, and was just wondering if you guys know how to fix it.

Im sure that ive you have selected party chat you cant hear people in the game, just those that are in your party. Change the settings to in game chat.

But even when he is playing without a party they are all muted.

i dont think its parental controls check preferences in you xbox guide scroll down to settings and press preferences then voice and see if mess around with the settings you will be bound to get something in there
