how do i hook my vizio smart tv to my radio

Solution
Are you trying to get the TV sound to play on your "radio" speakers? Your TV probably has an optical audio output ( a sort of square hole with a cover with nothing protruding from the TV) and the "radio", if it has an input it is probably 2 RCA jacks.
You would need on of these:

and the optical and RCA audio cable to get it working. Your TV volume control will not affect the volume from the "radio" so if it doesn't have a remote it might be inconvenient.
