Cambridge Soundwork 4.1 pc system - rear speakers mute


Jul 24, 2013
I can't use the rear speakers in a Cambridge soundworks fourpoint pc system ( ) I mean, the front speakers work, the subwoofer works too, but the rear speakers don't work. I tried to invert the speakers, but only the two plugged in the "front" jack work.

I had to format my winXP pc last week, and now i don't have the installation cd or floppy. The system is very old, i think 10 or more years old, but last week it worked. Can anyone suggest me where can i take the driver? I emailed them asking for support, but they just suggested me to buy their new products...
