(I live in a large house divided into 9 flags)My speakers (Logitech Z4) have, for about, 6 months or so, randomly had a large burst of sound, like an explosion crackling noise comes on for a second. It's really loud, often makes me jump if my speakers are turned up. I think I read somewhere it is relating to someone turning a switch (or something) on in another flat. Has anyone had this trouble or know anything how to solve it?
I have no idea how to diagnose it or even google for a solution...
