Speakers emitting high pitched sound

Plugged into two different computers (via Front/Rear/Center plugs), my phone (via the auxiliary in jack), and nothing at all, the same behavior seems to occur. Firstly, it has nothing to do with my computer. It is also louder than the initial hum, to the point where it interferes with any sound that is currently playing.ĭiagnosis-wise, I have ruled out a few things. However, over the course of the next few weeks, the it began taking longer to subside, until, at this point, it never goes away. The whine is always present at speaker power-on, and initially subsided after a few minutes.

A few weeks later (about a month ago), my speaker system started emitting a high-pitched whistle / whine through the satellites. When any sound is playing, it drowns the buzzing sound out, so I just ignored it. About a month and a half ago, my speakers started emitting a soft mid-frequency buzzing sound. I have a Klipsch ProMedia 5.1 speaker system (which I adore). I saw a lot of great advice / answers in other posts, so I figure I'll give my issue a shot.
