Query: Doesnt seem to work

I bought this audio cable to hook my macbook up to my Samsung tv (along with the DVI to HDMI converter and HDMI cable) and it doesn't seem to work! There are many different spots on the back of my tv to plug audio cables into and I have tried them all but there is no sound coming through. Is there something I need to do to my TV or macbook that i'm not aware of?? If anyone can help please do! I would love to have given this product a good review! At least it was under 3 bucks.. not much of a loss there.
