My laptop makes a static sound. It's constant, from when I turn on the computer. If I mute it, then the static goes away. I've tried plugging in headphones, which doesn't solve the problem. The speakers stop, but then the headphones have static. I've tried muting it while the headphones are plugged in, but the static continues. Any help? By the way, I bought this laptop last week.

Take them back for replacement as they are defective. You cannot repair them yourself and the cost for technical service is more than the set is worth.

Is the noise coming out of your speakers or is there a fan or some other device in the laptop that is generating this noise?

Click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it in XP try swapping the speakers around if the problem still persists either the speaker is faulty or the speakers plug/outlet is usually at the back of the computer or to if a laptop on the side you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems Hope this helps.

Laptop or Desktop ?
Try swapping the speakers around to see if the problem is in the speaker itself.

Volume problems on computers often happen for a variety of reasons.

Volume troubleshooting, however, is one of the easiest problems to troubleshoot because there are only a few things that usually cause the problems.

Usually the problem isn't even an error but just merely an adjustment that needs to be made.

Test your speakers.

This is the first thing you should check if you can't hear anything coming out of your computer. First try turning up the volume know and make sure you are in fact turning the volume knob and not a tone or balance knob.

Make sure the speakers are completely plugged in to the wall and the computer. Test with another set of speakers or headphones after you have done this.

Check the computer volume level.

On the taskbar is a volume icon, which usually looks like a small speaker.

Click on the icon and turn the volume up.

Make sure it has not been muted.

Double clicking on the icon will bring up a panel of several volume controls.

Try turning up the volume on each slider.

Go to Control Panel and choose "Sounds and Audio Devices."

Under the volume tab, click speaker volume and turn up the level if needed.

Turn up the application volume. Most programs that use sound have an additional volume control just for that program.

Find the volume control and turn it up.

Usually it is located in the lower right or left corner on the program, but you may have to search for it.

Troubleshoot the sound card.

Download the latest drivers from your sound card manufacturer's website.

Go to Control panel > System > Hardware > Device Manager. Click on "Sound, Video and Game Controllers."

Click on your sound card, select the driver tab and then click on "Update Driver."

Point to the file where you saved the latest drivers from the website.

After this, restart your computer.

The speaker plug/outlets is usually at the back of the computer or if its a laptop on the side

you will have to open up the computer to check the lead attached to the rear of the input plug make

sure the connection is good with no dust as dust causes static electricity

clean your computer of dust using a can of compressed air or fine air blower from a compressor making VERY sure that there is

no MOISTURE in the air line specifically around the sound card and the CPU central processing unit

dust causes static to build up in a computer

If this doesn't solve your problem, try reseating the sound card into your computer.

Hope this helps

if your speakers are near to some electronic devices you'll get theses static noises try to keep them away from electronic devices which solves it very easily..

jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.

Replace the internal speakers. Rather large pain since you have to almost disassemble the system to get to them.

What sort of computer do you have? Is it a laptop or desktop? Many laptops have this problem and it is quite widespread in laptops. The crackling or humming noise could be a result of interference from the mains power signal.

If it's a laptop, try running it on battery alone (take out the mains power cord). My laptop has this kind of noise in speakers when running on mains electrical supply, but it goes away like magic when I run it on battery.

A more long-term solution is to buy a 'Ground Loop Isolator' and insert it between your computer and the speakers/earphones. They are quite cheap and you could get it for under £10. It removes all static noise and you'll hear crystal clear sound.

When we turn our TV the humming and buzzing begins! We cn mute it and it goes away and then it when we turn the sound back on the sound is back! How can we fix this?
