I backed up Deus Ex on the hdd with dvd2xbox, but when I play it I don't get any sound. I get sound on the Eidos screen, the next screen, the Thief video, and in the nice choppy intro movie for the game. I just don't get any sound at the title screen or during the game. I've looked around to see if anyone else had this problem, but I could only find stuff about people not being able to get the game to work at all. Any help will be greatly appreciated.

Nevermind. My bad.

I have the same problem, were you able to solve this!
