I've had this problem for sometime now. Using Windows 7, anytime I close an application, website, game, etc. that has sound in it (i.e. music) I get a hum from my speakers the same volume as the sound in the app. this will stay on until I launch another app with sound. Example, if I'm playing an AVI using windows media player, and I stop the video berfore the end and close the media player, I will get this "Hummmmmmmmmm" until I relaunch the media player or another application with sound. If I allow the video to playout there is no hum. But If I'm playing a PC game, when I close the game I get the same problem. Tried new drivers to no avail. Please help...

Control Panel > Hardware and sound > Underneath sound in small writing click change system sounds > At the top click sounds on the window that opened > You should see something that says 'close program' click that > There should be a drop down list click that and choose 'No sound'. Your problem should be solved. Tell me if you have further problems.

Assuming it's a desktop PC setup with active speakers powered from an a/c adapter, the buzz could be coming from electrical interference generated by the a/c adapter if it's an "unregulated" type.

See if moving your wires or jiggling the jacks makes any difference, too, in case there is a bad connection or ground somewhere.

sorry it took so long to get back with my response. I tried what you said to do "computer12345" but it still does it. It is NOT bad ground or electrical interference. If you let the video run it's natural course to the end the hum does not happen. It only happens if you close a video before it's natural end. It's as if there is some kind of sound interupt that is not happening when you hit the stop button. The hum actually will change pitches in pitch with the sound that was playing at the time you hit stop. i.e if it is a soprano tone, the hum is higher pitched, if it is a bass tone, the hum is a lower pitch, much like it is humming the last note sent to the player, maybe its' not a hum but an annoying "stutter" of the last sound.
