I have a Motorola DCT2200 and a Yamaha RXV-1000. The DCT has coax digital out. With the Yamaha set to auto on cable/Sat on Digital cable channels there is no problem. The display shows Auto:PCM, and I have sound. When I am in the standard cable band I have no sound and the display show Auto:PCM. If I switch the Yamaha to Analog I have sound. If when the Yamaha is in Auto and I unplug the coax I have sound and the display shows Auto:Analog. There must be some signal (but no audio) on the digital out of the DCT.

Any help on this?

Thanks,
