Connect RCA Laptop to Optical or Coaxial TV Audio

Your Laptop (Composite (RCA) Out - Very Unlikely)



Your TV (Optical In)
OR
Your TV (Coaxial In)

Considering this is so rare, I'm not sure why I'm even posting it, but I figured since it's a possibility I might as well list it if someone is really desperate. I recommend this method as an absolute last resort. Using this converter will not up-scale your analog stereo output (via RCA) to a clearer digital version through optical or coaxial, so this method really just seems silly. That being said, if your laptop has a composite (RCA) output you can connect it to your TV through an optical or coaxial input using the following items.



Composite (RCA) Cable

The RCA cable will carry an analog signal from your laptop to the analog-to-digital converter before getting to your TV. To use this cable, plug one end into the red and white RCA OUTPUT ports on your laptop and the other end into the red and white RCA INPUT ports on the analog-to-digital converter.

RCA to Coaxial/Optical Audio Converter

This device converts an analog RCA signal originating from your laptop and converts it to a digital coaxial or optical signal for use on your TV. Make sure the RCA cables coming from your laptop are plugged into the converter's INPUT and the coaxial or optical cables are plugged into the converter's OUTPUT.

Coaxial Cable

The coaxial cable carries a digital signal from the analog-to-digital converter to your TV. Make sure one end of your coaxial cable is plugged into the OUTPUT of your analog-to-digital converter and the other end is plugged into your TV's coaxial INPUT.

Optical (Toslink) Cable

If you don't wish to use a coaxial cable with this device to connect your laptop to your TV you may elect to use an optical cable instead. The optical cable carries a digital signal from the analog-to-digital converter to your TV. Make sure one end of your optical cable is plugged into the OUTPUT of your analog-to-digital converter and the other end is plugged into your TV's optical INPUT.
