Hi All,

I've moved my gaming PC which has a Creative Labs Xtreme Music card in it - all analogue outputs with no optical it seems. I have a 3.5mm cable going through to a L/R input on the amplifier - these seems to run Pro Logic. In games such as Dragon Age or TF2 you can hear some faint background sound on the rears but if you fire a grenade or start talking to somebody then turn around the voice cuts off instead of coming out of the rears. I've done a bit of reading on 5.1 PC gaming and it's still confusing me a little.

Would you recommend I upgrade to a better card with optical perhaps or can I purchase some extra cables and use the rest of the outputs into my amp ( it has a multi ch in section which I could use ).

Basically I would just like to have 5.1 audio like I do for my consoles which support it out of the box over optical.

Any help really appreciated.
 
Ok, that makes a lot of sense. One thing confusing me with this :

Line 3 ( main fronts )will be a 3.5mm > L/R RCA into the 'Front' Multi CH in port
Line 2 ( center ) the amp only has a single port for Center and one for Subwoofer, would this just be a 3.5mm > 3.5mm center port in the Multi CH in ?
Line 1 ( rears ) will be a 3.5mm > L/R RCA into the 'Rears' Multi CH in port

Does that look correct?
 
Hmm yeah that's what i was thinking. The only thing confusing me is the center speaker. That cable outputs to l/r but on the multi ch in there is
a single socket for center, unlike the rear and fronts which have l and r. I think I'll need a single 3.5mm for the front instead of one of those above you linked.
 
Marsman - just thought I'd let you know - got the cables through. Cabled it all up, took a couple minutes working out which was Center and Sub but using the windows control panel to test each speaker got it going. Games all output in 5.1 now :) Thanks for all the help, really appreciate your comments and assistance.
