All home theater receivers have this connector. You should use it if both your computer and receiver have it and if your PC and/or your receiver don’t have optical digital connection.
For this connection you will need a simple RCA-RCA mono cable, like the one shown on Figure 9. Usually home theater receivers come with a spare cable for this kind of connection, where the plugs are orange. The color isn’t important; you can use a cable with red, white, black, yellow, pink or whatever color plug.

Now everything is connected and should work just fine. You need to change the input selector on your receiver to “DVD In”, “Digital DVD In” or similar.
