I have a pair of 7.1 Astro MLG headphones which have worked fantastically in all previous Halo versions. But in Halo 4 I cannot hear anything behind me. In previous Halos I could hear people sneaking up behind me. But in Halo 4 I don't even hear a ghost or a hog coming from behind me until it has splattered me. Anyone else have this issue? Anyone have a fix for it? Or is it a 343 problem?

Please turn off the music in the matchmaking lobby! It is like being water-boarded... over and over and over again the same 12 second sound track being drilled into the brain. It's so aggravating I want to tear my headphones off between matches, but then I can't enjoy conversation w/ my friends.
