This has been happening for a while, and it's starting to drive me up the wall. It is very quiet, but can still be heard.
Is it possible the speakers are picking up radio, because they are older (like from 2007-ish) and they have analog cable, and not USB one?
EDIT: I specifically would like to know if it's possible the problem to be related to the nature of the cable (analog), and if USB cables would not have this problem.
