How do you hook up a sound bar to my 65" curve rca TV it doesn't have a optical hook up

[leonardjohnson45]

I have a blackweb sound bar that I am trying to hook up to my 65" curve TV it doesn't have any optical ports in the back so I purchased a cord that has red and white on both ends but I still can't get the sound to come in

Need some details about the TV, what outputs does it have? Brand/model? Red/white cord would be just a simple RCA audio, not a lot of TVs now have that as an audio output.
