I just bought the Creative SBS 560 5.1 Speaker system, and I have an old Creative Live Blaster soundcard. It has Line Out for Front speakers, Line Out for Rear speakers, and a digital out port. I plugged the center speaker in the digital out port, but it's very very static-ky that I'd have to unplug it. The sound quality is so horrible from the center speaker - anyone know why? I've already d/led the lastest update.
