Query: It below my expectation

I purchased this product to use it with my 5.1 speakers system. Though it detects all the speakers, the output is not satisfactory. As I'm an Electronic Engineer, I can clearly say that it filters out even some of the frequencies which are required. And moreover the output power is much below my expectation. If you are just bothered to get the sound on all the speakers, then this is a good choice, cos there are no competitors for this product. But if you want the real experience, go for a sound card which connects to your motherboard directly. Laptop owners, you have no choice!!
