Okay, I've been fighting with this thing for about 2 hours now and can't get it to work. Nothing. The only sound I get is a subtle "thump" from the subwoofer when I turn on the control unit. I have tried only the simplest connections, analog TV audio out (no joy), and analog DVD player (again, no joy). Even pressed 'reset' and then 'test'... nothing. is this thing dead or am I just that stupid?
