I cannot get my computer to do surround sound when gaming. Ihave Medal of Honour: Warchest (Allied Assault, Breakthrough, Spearhead), Call of Duty including United Offensive, and now Battlefield 2.
Initially I thought it was just the games I had were older and did not support, but I'm suie Battlefield 2 must support surround

There certainly appear to be options in the game setup for it as hardware or software, yet all I get is sound from the two front speakers, nothing from the rear
I'm running windows XP SP2, fully patched with current drivers for the motherboard, etc. The motherboard is a Gigabyte K8NS Ultra 939 whcih has an on board sound card, controller nVidea(ooEA), codec ALC850, DirectX 9.0. Speakers are Creative Labs Inspire 5.1 5300 EAX.
I've checked the setup of my PC and as far as I can tell all appears to be normal. The PC runs a software application to detect which speaker plugs are connected "Realtek Sound Manager" which came with the motherboard. doing the hardware speaker tests all appears to be correct, in that sound plays from each of the 6 speakers in the correct turn. Similarly it says all the plugs are correctly connected via UAJ sensing (whatever that is).
Anyone got any thoughts. Thanks in advance.
