Cable tv music analogue or digital?


I was trying to improve the quality of the sound coming from my cable tv box, sometimes I like to listen to the jazz station. I ran a regular rca jack from the analogue outs on the cable box to the analogue inputs on my pre-amp, the sound is ok, but I wanted to improve the sound. so I ran a cable from the digital coax output on the cable box to the coaxe input on my Cary 306/200 cdp/dac and then into the pre-amp. guess what, no audio signal coming from the music channels but I do get an audio signal coming from the regular tv channels. Is it possible that regular tv signals are broadcasting in digital but the music channelis still going out in analogue? what else could it be.

You did not say which model of cable box you have but on mine I had to change the output setting from Dolby to PCM to get it to output digital for the music channels. You do this on the set up on the cable box.
Jaillo,
I have a "Pace" box, I looked in the menu, on on the box and can't see anyway to ajust this.

Joeb: I believe it stands for Pulse Code Modulation. Let's see what those more knowledgeable come back with.
Ok, well, while I'm waiting on more info, here's another weak link. I have a cheap dvd. I ran the audio rca outputs from the dvd into my pre-amp, but the music sucks. It does have a digital toslink output, I wonder if I can run that into my Cary digital toslink input and just pipe the audio signal out so I can listen to concerts with some improvement? I gotta bad feeling the upgrade bug is starting to mutate again.
