I just bought logitech z-5500 5.1 for my laptop and of course along with a creative audigy 2 to complement it. Although i can hear the difference if i use my creative audigy or not, its not really much of a difference, or maybe i am going deaf. I went to do a test check on my logitech z-5500 and all the speakers seems to be working fine (this includes all the connection as well). Next i install my creative audigy 2 preparing myself to be blowen away by the major sound difference, but ....to my disappointment, i dont really hear a major difference. After the installation, i went to test the speakers from the creative audigy 2 program and only my front left and front right speaker are working .... If anyone have the same problem before or know how to solve it, i will be more than grateful. Actually I was thinking if the cable given by creative is defective or not but i am not able to test it out yet and its kinda unlikely as well.
