I need help for the Logitech X140 speakers I am having. When I was using these speakers on my windows XP they are working fine but from when I have upgraded my system to window 7 the problem started. Actually I am not able to hear any sound from my speakers. I thought that may be it require some kind of drivers. I have tried to update the drivers but it did not help. Can anybody explain me why Logitech x-140 speakers are not working on Window 7?
