    my soundcard is realtek high definition audio and the speakers are teac-xt6 they are 5.1 the problem still remains ...e.g. the woofer worked two days ago for an hour or something and then stopped again.

    u should try to isolate the problem...hook the speakers up to something other than ur pc... also, on ur PC open the realtek control panel (just search for REALTEK in ur start menu) and make sure u have speaker configuration set to 5.1 speaker...also try enabling/disabling BASS MANAGEMENT to see if it has any effect.. I would also want to check the cables connecting the sound system to the pc

    The problem is likely the crossover settings. You very likely will notice that the sub works in Games and Movies that have a 5.1 dedicated sound stream (Dolby Digital/DTS). In Windows, set your fronts and rears to small. This should reroute the lower frequencies to the sub woofer. (go to playback devices and click "configure" on your default one)

    EDIT: untick the checkboxes in the realtek config screen as seen above that say "full range speakers". Doing this will not put the full range of sound to your fronts and rears (ie, high and low range frequencies) and will put the low range out on the sub like it's supposed to be.
    TIP: Just because your speakers are big, don't tell Windows/Realtek that if you want to actually USE your sub ;)

    Sorry one more thing, buy a better sound card - Realteks have rubbish features and crappy signal to noise ratios!
