Can I have true 6 channel (5.1) surround sound with this this?

I'm thinking of buying this sound decoder

Can't post the URL cuz i havent made 5 posts but just search for "5.1 sound decoder" on ebay and its the first one there. Says something like "HD Audio Rush 5.1 Gear Sound Decoder for DM500s xbox360"

I want to use it with my PS3 via its optical output and with my logitech X-530 PC speakers which ouput to the three 3.5mm jacks on that box :)

I'm just not 100% if this will work and on the picture it cant see any optical ports... Is that just because those black squares are caps covering them?

Thanks for any answers guys :)

As far as true DD 5.1 and your PS3 goes with the X-530's the answer is no. It does not have any digital inputs (optical/coax), so all you will get is simulated surround. There is a Logitech game console adapter for around $10 or just get a generic 1 for around half.

You would need something like the Z5500 to do what you are asking.
