Why Doesn't my Digital Cable Box Talk to my Surround Receiver?

I have a Motorola Digital Cable Set Top box. It has an orange-coded Coax output that appears to be a digital audio output. I connected this to a digital audio coax input to my Onkyo receiver, but can't get it to work. I tried turning on the digital audio capablity on the set top box setup, even tried swapping out the box that I had on my TV upstairs. Even connected it to the same coax input that my DVD was hooked up to no avail. Suddenlink tech support has been useless. What am I doing wrong?

If the cable box has " audio- out " on it , run an audio cable ( likely 2 male connectors on each end, red & white), from the audio-out on the cable box to the " audio-in " on the receiver.

That coax is likely meant to attach the between the TV & the cable box for the cable signal. There should be a coax cable coming in from outside, hook that to cable in on cable box, and use the other coax to go from cable -out on cable box to cable-in on the TV. Sounds like you're doing everything right.....

Does your receiver have optical audio? if so, maybe you could scrap the whole coax idea and go with optical audio!! I have yet to actually hear a Digital Cable Box talk to anything. I think at this point Motorola and the human race in general lack the ability to build something with truly articifical intelligence to make it talk. The closest you might come is text-to-speech playback, but even then, I don't think your surround sound speaker will be able to understand. =0( You need to go into your Onkyo's "audio selector" menu and designate the input setting you use for watching TV to "audio = auto coax 1"

That should activate the digital coax input on the reciever.
