Okay, I have this motherboard (ECS RS485M) http://www.newegg.com/Product/Prod [...] 6813135011 and these speakers (Logitech x-220) http://www.shopping.com/xPO-Logite [...] KER_SYSTEM My problem is, I can plug the speakers up into the front audio port on my case, but the rear ports give me no sound. Could someone point me in the right direction of what to check?
