I need help getting my sub woofer working

[casinomadrid]

I have been trying like crazy to get this working but nothing I have done has worked. so i have turned to the toms hardware community, Because you guys and gals are good at solving problems. I have this speaker setup (http/gx-gaming.com/?action=products_detail&wtype=feature&id=10).

The speakers are a 2.1 setup and I have IDT integrated HD audio for sound, But I can not get the bass to produce any sound what so ever and searching google has not produced results either. I have pictures of my settings and my config of the speakers here as well. Sorry if those are not clear enough and if you need more details I will gladly give them.
here is the link for the pictures http/pc21audio.imgur.com/all/

2.1 speakers almost always route the bass internally, the connection is usually from the sub to the PC and then the sub had an internal crossover to send the higher frequencies to the smaller speakers. If there is not bass either you have it turned down on the sub or there is a lose or broken wire or the speakers are broken.
