Hi AudioBob
If your DVD Audio player has multichannel analog outputs for each channel (Front L/R, Surround L/R, Center and Subwoofer) you have to connect these cables to either your receiver, your processor or your ICBM Bass Management Module. You should also connect the toslink or coax to the receiver/processor for your non-direct formats. If you only connected a coax/toslink and select "direct" that means the pure, unprocessed analog signal, you won't get any output. You have to coordinate your receiver/processor with your DVD Audio player - direct mode on each, then you will get your DVD Audio output.
What kind of DVD Audio player are you using? I use a Toshiba SD9200, blows me away.
