I just noticed while paused on a television program that a faint ticking noise was coming from my speakers. The ticking comes from both speakers, the headphone jack, and if I crank the volume the noise does get louder. The noise is there whether audio is playing through it or not - as long as the amp is on and you have something connected to listen to, you hear the chirping/ticking. About once a second.
Anyone know what this could be?
