Cannot hear each other when playing on same Xbox console

I'm almost positive that no matter what headset you use, you cannot hear each other using the same console.

Hi there.What exactly is going on when you try to play them both? Generally they won't be able to hear each other over LIVE when they're on the same console, but others in the Party should be able to hear them.

Hey there, Leaky Clant! If you guys are both in the same house and your NAT is moderate, then this would be why you guys cannot hear each other. You will need to a router that can support both consoles with Open NAT in order to hear each other while playing
in the same house. You can check out our
Networking Hardware Information forums for your router to see if it doesn't support multiple consoles and to find routers that should be able to handle that.

Keep us updated on the situation!

I assume they all are in party, as he is in a group. Xbox friend can talk to PS4 friend and Xbox son can talk to PS4 friend. But in the same game Xbox friend cannot talk to Xbox son. Leaving PS4 friend to relay each of the XBoxs to each other.

I have the same problem on CoD MW and I have my the other Xbox player as an Xbox friend and in game friend but cannot hear each other.

Yes, two people could play online at the same time, both with headsets, and join a party and talk to others, but the two may not be able to hear each other through headsets (because they're on the same console). So both users should be able to hear everyone
else, and everyone else hears both of them, but the two might not be able to hear each other through headsets and would need to rely on hearing each other without microphone/headset.

I hope this helps.
