I would just wait until the game comes out, the demo I got of the marketplace was buggy, and played two audio tracks at the same time.
In other words it was rushed and crappy.
The demo was not buggy with audio problems on my end... I've been playing alot of the demo (to learn the moves)
You better send your XBox back. Sounds like your 360 was rushed and crappy.
