It's the "wrong" one becoz your TV is getting your Mac Book Pro's video from the HDMI input, but your MBP's audio is connectted to another video input (that takes in analog RCA signal.) Their path don't cross. 
To make your setup work, connect the RCA output to a dedicated amp.
Yup that's the cable!
Err, what if I don't have a dedicated amp? :X
Thanks for the heads up!
