I have 4 Insignia Bookshelf speakers and a powered sub woofer hooked up to a 5.1 Sony receiver. I have a digital coax run from my Extreme Music to the receiver. I just got the Home Theater cable from Creative so I would be able to get directional sound again in my games. I hooked it up per the instructions, my receiver has a multichannel input, and everything works except the sub woofer. It is connected to the receiver via a sub woofer cable to the sub woofer output. I have been trying all the settings in the drivers but no luck. Do I have to connect the sub in a different way to get to work with the analog cable. Thanks
