Check the options in the audio controls for the sound card or you just have the rear speakers plugged into the front speaker ports. And if the front to rear sounds are reversed but you have the in the right ports, just plug them into the "wrong" ports and it should reverse to sounding normal.
Thanks for the reply, I've looked into the settings of realtek and x-Pro and I can't find anything that reverses them. And as for the ports I can safely say their in the correct ports however I can't just simply switch them round as the front right is plugged in via VGA where as the others are all jacks.
