Video:
Coax from wall to cable box IN. S-video OUT from cable box to receiver S-video IN (TV/CBL). Receiver S-video/component/HDMI OUT to monitor S-video/component/HDMI IN.
Audio:
Cable box L & R analog audio OUT to receiver L & R analog audio IN (TV/CBL).
If your receiver doesn't have a digital audio coax (S/PDIF) IN for TV/CBL, your are probably stuck with analog/RCA audio out from the cable box. The only other option would be to get a S/PDIF coax-to-optical adapter/converter (
something like this). Then you could run the digital coax OUT from the cable box to the receiver's optical IN (TV/CBL).
