My speaker set is a Creative FPS2000 Digital. As of late I've been getting ticking sounds from my speakers. I tested them by leaving my computer off and just turning on the speakers, and they tick every so often, so its not my soundcard. The tick is like someone lightly flicking the table. It gets REALLY annoying. Whats weird is that only the front two speakers tick, and the back two are fine. I've rewired my entire set and I don't know what the problem is.
