How to Connect Samsung 32" with no optical output to Polk 2000SB via a Comcast cable box? I connected the optical output to c

I have a Samsung 32" attached to a Comcast HD cable box. I connected a Polk 2000SB to the cable box since the TC has no optical output but the cable box does. The SB has power - everthing is on, but no sound from the SB. What else do I have to do?

Also have Apple TV and I understand netflix comes through with dolby sound - the Samsung TV has no digital preference (dolby vrs something else or dolby off/on settings) - does that mean it is only in dolby format which the Polk 2000SB does not decode?
