Hello,

I just got the Logitech z506 5.1 speakersand I am having some problems getting the sub-woofer to work with 5.1 sound. I am using the audio that came with my motherboard and although the sub-woofer is functional when playing from a stereo source with the speaker fill option enabled when testing from the sound option in the control panel using the 5.1 option each individual speaker works except nothing from the sub-woofer. I am using the VIA HD audio deck software that came with my pc. The wires are colour coded and are setup as shown in image below, any help would be appreciated.
