Connecting Home Cinema to PC help please

[knightsy]

Hi there

I have my PC and a Samsung HT-DB120 home theatre system. It has these connections:

Composite Video out
Component Video out
S-Video out
Digital Audio in(optical)
Composite Audio in

I would like to buy a medium priced soundcard and the lead to go along with it in order for me to use the system with my pc to get surround sound in games. I would like this to be as simple to do as possible. But not so simple I lose out on too much.

Can you recommend me a soundcard and lead to use please? (I like creative)

I don't have a clue what I need to buy, especially in terms of a lead.

Thanks

Well I guess you could either simply use pretty much any soundcard and use something like this

to connect to your analogue audio in on your amp, or go for something that has an optical out like this http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=3701&item=5150758893&rd=1&ss

and connect to optical in using something like

Would you be able to output games via S/PDIF though? I guess you can with an NForce based mobo as it has onboard hardware dolby encoding.
