Solved! Seiki smart TV, what RCA Jack's, ad roko

Solution
The RCA jacks of your TV are the yellow, white and red ports that you can see usually at the back or at the side of the TV. You need to use those cables and other end will go to your surround sound. If you can also see on the TV the port says audio optical out, you can use an optical cable too to connect to the surround.
