The clicking sound happens when i'm not doing anything, and goes away or is drowned out when I play music, watch videos etc.... It's occuring in my front right and rear left speaker, and it is continuous and more obvious when i turn up the volume. The only thing is when I mute everything, i can still hear the clicking. I disconnected the connections to my sound card and still the clicking persists. Finally i switched my speakers around, but the clicking is coming form the same channel (ie the speakers are fine, its Front Right and Rear Left channels that are the culprits) Any help would be much appreciated.
