I hear him right at the start but then I get a low bandwith message come up and dont hear anymore.

My line is 4mb down and 756KB upload, surely thats enough.

Anyone else heard him? Everyone I have spoken to has never heard him during the game.

Cmon Microsoft sort it out!!!!!! I know its beta but the game is crap without the live host being there. The game just have massive long pauses without.
