Remember that the Roku doesn't support Dolby Digital, only Dolby Digital Plus, and DD+ can only be passed thru HDMI. Make sure your Roku is set to stereo/PCM (sorry, I don't have the exact setting in front of me as I'm at work) not DD+, because I'm guessing if your AVR has not HDMI that it doesn't support DD+.
Cable works, can see red light

Red light glowing from TV optical output, yes.
Once plugged in to the TV, the other end of the cable glows red.
I appreciate mentioning the possibility of a cap, that seems to be a common issue that's infrequently answered for other people, having gone thru many threads while researching this... that said - no, the cap is not on.
Cable clicks into place on both the TV and the AVR, yes.

I will try everything again when I get home, but yes, I did connect it to the DTV/CBL port, and selected that as the input. I also tried the CD input with the CD port. Also tried the ports with the opposite inputs. Nothing produced any sound whatsoever. Made sure to have the volume up quite loud, with a video playing the entire time to make sure i'd detect any sound.
Also, yes, the audio select setting is on Auto, not analog.
My best guess of the cause at this point is in the cable, so I've ordered a new one. I don't see how it could be the cable given that I can see the red light on the opposite end of the cable once one end is plugged into the TV output, but I figure it's worth trying. Maybe it's damaged instead of fully broken... But from what I've read, that would lead to messed up/intermittent audio, not no audio at all.
