Hey i'm having problems with party chat but its nothing I've seen before. Firstly me and a friend play Destiny. In game chat is fine, we can hear each other its all good. But when we join a party started by either of us they can't hear me speak....I can hear them though. Both of our NAT settings are open. I've joined parties with other players on Destiny and its fine we can all hear each other. I've tried looking at settings to see if I have changed something but I can't find anything. Also this seems to have started after I upgraded routers. But like I said both NAT`s are open. Are there any settings I may have missed? Any help is greatly appreciated, thanks.
