I am wondering what the problem could be here. I have the Logitech Z-560 computer speakers and just like a couple older radios i had that have a volume control knob.. when i adjust the volume either up and down on the unit itself there is crackling and popping to be hear from all the speakers. The speakers are not blown, i can crank this thing and there is no distortion its just when i manually adjust the volume. Any ideas as to what i could do to fix the prob? Warrenty over, i've tried contacting Logitech and they were of no help. Only thing i can think of is to open the volume control box but i dont know what i'd be looking for that would be causing the problem. http://www.softmag.no/bilder/logitec...0_hoytaler.jpg thats an image of what it looks like. thanks for any help!
