My problem is.... there is no fiber optic port on the new xbox 360? My old one had one... why are we moving 'backwards'?
Are you sure your old 360 had an optical digital output? I've owned four 360's and a 360 slim and everyone needed the adapter cranium2001 posted for my Turtle beaches. I never saw the HDMI audio converter Kanooke linked, but that would work as well. How long did you have your older 360 that had issues?
