Ok ... it's nothing bad or anything, but i've been wondering about this for over a year now!
I am sitting at my pc and i've got my speakers on, theres no sound playing but there is some quiet static coming out of them ... normal right ?! But heres the weird thing: The static makes noises that fit to whatever the pc is doing. When i minimize a window the static makes a certain kind of buzzing, when i maximize the window it makes another type of buzzing noise. The same for opening programs, whenever i do that it makes a kind of high pitched noise. Pretty much everything i do makes the speakers give off a certain specific sound.
So i though, maybe it's just the pc sending these to the speakers. I unplugged the speakers from the computer but they still give off the sounds.
I put on my MP3 player and muted the sound, and that too made the noises when the headphones were within a few metres of the computer ....
... am i going crazy or is this normal ???
