What nouns card can I buy that supports 5.1 through the rank within?

I enjoy a new TV that simply has RCA out for the nouns, no coaxial or digital. The sound card contained by the computer has simply 2 speaker support through the line contained by. I do not want to buy a brand new stereo system for the tv I want to use my computers 5.1 system. Is nearby a sound card that will allow me to plug my tv within and get 5.1? I be thinking about the Creative SOUND BLASTER X-Fi Fatal1ty that comes next to the 5.1 bay extra that have auxillary line within jacks. Thanks

If the tv only have two rca (left and right), it doesn't support 5.1. You can only try to simulate it near the software on the computer (get a converter from rca to the 1/8 stereo plug). If the tv has adjectives 5 connections, then if the nouns card actually supports 5.1, consequently there is 3 plugs for it (again converters cords from rca to 1/8).
