Answer 1

setting on the xbox under options, Chang audio options

Answer 2

Don't use the red and white cables for audio, go out and buy an optical cable, this should run from your 360 to you sound receiver, not your TV.

Answer 3

Did you Elite come with the audio adapter?  Are you plugging the audio into a receiver or right into the TV?

Answer 4

buy a digital fiber optic cable and run it into your receiver from the audio thingy that comes with elites or just buy an A/V receiver with HDMI inputs/outputs and just run your 360 in through that to solve all your problemos
