I can hear Right-Left and a little with the Subwoofer/Centre but the back speakers are dead, Everything is plugged in propoerly but they just dont work
Do you have 5.1/7.1 soudcard??

Aww how does one check? I'm never bothered about that stuff -______-''
I had same problem bought new soundcard and it works now. Or go to: Control Panel-Sounds and audio devices advanced and set it to 5.1/7.1

If u have only 3(blue, green, pink) plug-in holes then it isnt 5.1 i have 6 plug-in holes.

Dont know where to check it. How old is your computer?

2 and a half years old. It sould support 5.1 : /
My old one was 3 years old. I think you dont got 5.1 soudncard thats the problem. 2 years its old.

fine : / guess I'll buy a new soundcard too then.
