I've never been able to hear the lobby when i'm in party chat, isn't that the point?
I've always used it so I can talk to my party and not the lobby, but in the other CoDs I was able to still hear the lobby.
While a lot of the people on this game irritate me and need to be muted, there are sometimes that you overhear a conversation that can make you laugh through the whole match. --- To understand the future, we must go back in time
on previous cods you go through the xbox menu and go to the sound settings put it on play through headset and speakers which would allow you to hear your party via headset and lobby via your tv. i don't know if it works for this game or with tb's because i haven't tried.
