I have digital cable through cox and the box I have is a scientific atlanta explorer 2100. Up until now I've been running the audio for cable from my tv to my receiver via the left/right rca stereo cable. I recently decided that I wanted to run things directly from the cable box to the receiver so I bought a dig. coaxial cable (the rca cable wasn't long enough). Now, I plugged the dig. audio cable into my receiver and cycled to that input, but I only get audio from some channels that way. If I plug the rca stereo cables back in while simultaneously having the digital coax cable plugged in, I can get audio on all channels via the aux. input w/ the rca cables and some channels via the digital coax cable if I switch to that input. Is this normal? I thought I should be able to get audio for all the channels via the digital coax cable - does my cable box need to be setup for that or...? Thanks much for any input! --note, right now the video from the cable box is going to the tv via normal coax, I still plan on running the cable straight to the tv and the audio to the receiver but should I use just a video rca cable so that all audio goes through the digital audio out on the receiver or will all the audio never go through that output?
