It's probbaly just electromagnetic interference (EMI) being picked up by the sound card or the speakers. The source could be something nearby (another card in the system, printer, cordless phone, etc). Cell phones are a frequent cause of this, if you keep your cell phone on or near your desk, it's probbaly the culprit. It could also be something farther away, like high-voltage lines near your house, or a broadcast tower.

If it is EMI, is sometimes helps to reroute the power and audio cables, so they aren't running alongside other cables. Do you have headphones you can plug in? If so, do they have the same behavior?

Also, you are sure it's the speakers, right? Not one of the fans inside the case?
