So the VGA cable only has analog stereo output? Weird.
If you want 5.1 audio, you will need an optical cable to input into your receiver. A home theater in a box (HTIB) is a good way to get started for a nominal amount. Alternatively, if you want to spend a little more, you can go all different directions. We can help guide you in whatever direction you want to go.
To help us help you, list out all of the gear you already own. Then list out what your budget is for home theater stuff. Then we can point you in the right direction!
