Did you check any settings on the TV? Standard settings might need to be changed?

Im looking i dont see anything that stands out I thought for sure I would get sound using the headphone jack to optical cable.

Is the problem with the TV or the Mac?

Unplug the cable from the TV and aim it at the wall or floor. Does it shine a spot of light? If so, then the trouble is the TV, else the trouble is computer settings.

Yes when I take the optical cable out of the Macbook the cable is red what is the problem?

Does your TV support taking HDMI AND optical audio on the same "channel." Most TV's only allow certain types of audio to couple with certain video inputs. Have you tried to see if the HDMI pairs with a 3.5" Minijack or RCA plugs? I know on my Samsung, HDMI1 is also labeled "DVI" and has a set of RCA red/white audio plugs to go with the port. I don't recall if the optical-in can be paired with HDMI1/DVI.

That's how I have my setup.

MDP-->DVI; DVI-->HDMI, and audio over 3.5mm-->RCA hooked upto HDMI/DVI1. Plus, if you're using your TV's speakers, there's no need for optical audio given they're not of high audio quality or 5.1 capability.
