Speakers popping during mac sleep

[kred321]

Whenever I put my mac mini to sleep, my speakers will make a pop sound about every second. The speakers are powered via usb cable plugged into the mac but they'll also pop if plugged into my dell. There's no popping if the speakers are plugged into my sleeping dell, when my mac is on, or if I turn the mac mini off. Any ideas?

Do you have a 3G phone next to those speakers or speaker wires?

No.

Just to add this pop sounds very similar to the "pop" i hear when i turn the speakers on i.e. could be turning on/off every second?
