There are three different types of audio connections that you can use to achieve 5.1 surround sound audio. The two most commonly used connections are optical and coaxial audio, which are used mostly to connect HDTVs and HD media players to surround sound systems. The third connection is analogue 5.1, which is almost entirely used for HD sound cards on computers. If your computer has analogue 5.1 connections and you'd like to convert to an optical audio connection, you can achieve this with a special converter box.

Place the converter box in a central location, such as between your computer and the optical audio device you want to connect to its analogue 5.1 output.
Plug the included power cord into the "DC/9V" port on the converter box and then into an electrical socket, power strip or surge protector.
Connect the three analogue 5.1 cables from your computer to the "SW/CE" (Subwoofer/Center), "FR/FL" (Front-right/Front-left) and "SR/SL" (Surround-right/Surround-left) ports on the converter box.
Insert an optical audio cable in the "D1" port on the converter box and then into the "Optical audio" port on your optical device (such as a surround sound receiver).
Press the "Power" button on the converter box to turn it on. Your computer's analogue 5.1 connection is now converted to digital optical and you can begin playing audio through the connection right away.
