Sorry for the cross post, but I am desparate. Ok, I spent all last night hooking up my new Denon 1803 and my Ascend Speakers (I hate running wire!). Anyway, I have a SA3100HD box with a digital coax audio out. I ran this audio out to the digital coax audio in on the back of the 1803. I switched the TV/DBS input on the Denon 1803 to receive the digital coax in. However, I have no sound! The DVD is running perfectly through the speakers, so I know the Denon 1803 works. Is there something in the service menu of the 3100 that needs to be switched for it to broadcast through the digital coax. One the settings menu for the Cox Digital Cable I have the "Dolby Digtial" box checked. Could it be a problem with the box? Please help. thx.
