How do you remove that static noise on your computer when you plug in your earphones?

Well, whenever I plug in my earphones to either my laptop or my desktop, I would hear static noise. Rather, on my second desktop's amplifier I've hear little or mostly no static at all (from a sound card, through a audio plug to RCA into the amplifier) and as well seems to be little suppressed using a toroid band on the plug of the earphones. Through little research, I've found out its the grounded prong fault, where different resistance causes this noises. So, without either doing A) REMOVE THE GROUNDED PONG or B) Grounded loop isolator, unless I could find a cheap one, how would I stop this problem? Snowy *Updated: No, muting it will defeated the purpose of having music on*

Before I go on, from your description, it seems like you're describing a short loud popping sound, when the headphones are being inserted into the socket, The grounded prong may not be properly grounded. I've got a cheap fake soundcard, and I've found that soldering a wire from the ground to an electrostatic discharge plug adaptor/earthing rod point really helps. Perhaps a cable to your computers case, or if there is a dedicated grounding point well that's even better. The noise is a buildup of static being suddenly released, and can damage your headphones/speakers/amps etc.. I have the noise when powering up my computer, it's because the static wasn't discharged properly.

Is the static there -only- when you plug in your earphones? Or is the static there -all- the time? If the static is there only while plugging it in, than it's normal. It's actually the sound of the connections being made when the plug passes thru the left & right audio connections(stereo). Like if you don't plug your earphones in all the way you only get sound on one side. If there's static there all the time once the earphones are plugged in, then it could be a number of things. The stereo port could be stripped, your earphone plug could be stripped, the speakers in your earphones could be worn out. Or, as stupid as it sounds, make sure your microphone is turned off. Some microphones are so sensitive enough that it either picks up on the noise coming thru the earphones/speakers and creates a vicious backcycle, or the electronics just interfere with each other. Also, if you have a cordless phone move it away from your computer. If you have a wifi router, check the setup and change the frequentcy channel on the router(then don't forget to change it on your laptop's wifi receiver). If you notice there's a horible noise on your cordless phone if it gets close to your wifi router, your phone and router is 'squaking' on the same frequency channel. You usually can't change your phone, but you can change the channel on your router(or it could be your neighbours router).

. A small amount of conductive grease should help.

Probably simpler than you were thinking of, but mute your sound when you plug in your phones. Is this enough of a problem to find a "better" solution? Is it a problem at all, or are you just curious?
