Was wondering if anyones had this problem and knows how to fix it (if possible at all). Ok so i have a Logitech X-530 5.1 speaker system. Had them for a couple years now, but recently if i move the volume knob on the back of the woofer, the woofer dies out and only the satellites produce any noise, if i press down on the knob, it works fine till i let go. if i turn it down a ways it works fine without having to press in on it, messing with the overall volume knob on the FR speaker doesn't kill off the woofer, nor does turning the bass up or down in my software. any help with this would be greatly appreciated.
