Why do my speakers make sounds when i am not listening to music?

With the subs on it feals and sounds like someone tapping their foot, but olny for about a minnet or two at a time. But it also makes a constant hum all the time.

You have a bad sound card, bad (loose) connection from the speakers to the sound card, the gain set WAY too high, or a source of interference nearby.

Cheap soundcard, maybe the standard one that came with the PC? A high quality replacement will solve.

Bad connection? Check to see if the jack wiggles in teh socket. If it does, and you see a pattern in your movements and the sound you are hearing, there you go.

Sources of interference? Magentic or electrical emitting devices near the speakers. Keep them clear of the monitor, and the CPU tower. If they are a good couple of feet from either - what else is on the same circuit? You may have an appliance somewhere else in the room that is generting interference on the electrical wire in the wall.

Gain is the easiest to test for. double-click the speaker icon in your start tray will bring up your sound board settings. Take everything down to the middle setting and see if that helps. Take the volume on the speakers down to midway. Did either of those two help? Then you need to experiment with the settings on that control panel until the hum goes away.

Hope this helps. Either your computer is haunted or they are the sounds of other programs you are using. This happened to me before, it's like an ad running, restart your computer or hit alt + cntrl + del and go under processes and look for something not normaly there. Hums and tappings in speakers are most commonly caused by a power cord getting tangled with a speaker cord. Also, microwaves & cordless phones can cause interference. If you've got 2 speaker lines sharing a port, then make sure the 2 positives are not touching any part of the 2 negatives and make sure they are not pushed into the port 'too far', as this will also cause your symptoms. Alas, since these are speakers being used on a computer, it's possible they are connected using the analog connection wire but your cd-rom is set to output 'digital'. If this is the case, then go to the DEVICE MANAGER and click on the properties for your cd-rom drive. If there's a check in the box DIGITAL, then take it out. This should help. If not, then a new sound card will :-) A) you have a bad sound card. Or B) its definetly has to be the static created inside the speakers, so the louder you turn up the speakers with no sound coming up its the static reacting with the movement. Mine does it too, and I get rid of the problem by trying to keep the speakers as clean as possible.
