I've just purchased this - http://www.cyber-acoustics.com/go/t...=products&category=Speakers&model=CA-5150R-uk and i'm having some problems with it. I'm fairly new to the whole 'PC sound system' thing. I connected all the speakers up correctly and plugged the power in and switched on. The manual says I can connect the system to an mp3 player or a CD player, i have tried this and nothing happens. When i switch on the system i cant here a faint buzzing noise coming from the subwoofer. I have just purchased the Creative Sound Blaster Live 5.1 but havent recieved it yet. I conected the system up to my 2 channel sound card in my PC but again no sound comes from it. Do i need to install specific drivers for the system?
