Can't get the optical audio to work"?

I’m trying to get the audio  to my receiver by using the optic output. I’ve tried everything, I can’t even get a red light at the optical cable, what am I doing wrong? 

I’ve had similar issues in the past with my optical cables.  Is your OC damaged?   Does the optical cable work on other devices?   If so,  I did this one time and I was able to get the red light back:

Remove OC from hub and your Receiver. 

Power off your Receiver.

Power on your Receiver.

Plug OC back into your Receiver.

Plug back into Hub.
