Do you have a 5.1 system or a 7.1 system? A 7.1 system has 8 speakers, not 7 and this one only supports 5.1 so you wont get your left and right sides only the fronts, rear, center and sub. I wouldnt have dropped that much on a sound system for a laptop, that also isnt a high quality USB interface, it only has 96KHz sampling, good desktop sound cards have 192KHz so you wont be getting the best quality sound but its better than just center and sub.

Its 7.1 . what about the upmix from 5.1 to 7.1 or 6.1 to 7.1 as there is a switch behind the sub.
