Laptop scratchy noise from the speakers

sounds like an internal connection problem. open access panel and check the solder connection is not broken or loose. Be sure the metal mesh jacket is not touching the lead wire as that would cause a scratchy noise and feedback, or maybe near the internal cable causing feedback

Small component board that controls sound could be faulty. It is near the bottom of the tv and the size of about a quarter. Another possible cause is "shorting" due to assembly ...If the speaker wire comes in contact with the metal at any point you will get this type of noise. Either way, you will need to take your tv apart to truely tell if the board is bad, or the wire has been cut slightly.


Thank you and best of luck!~

A scratchy sound may indicate that your speaker is clipping, or worse, blown. Make sure you are not running too much power to the speaker, or you run the risk of destroying your subwoofer. Reduce the power and see if the scratchy noise has gone away. If not, you may have damaged your voice coils by putting too much power through the speaker.

Sounds like you need a new sound card, also try to change speakers or test them in a other computer. I should test a other soundcard in the computer and if its sound OK then change it.

have you install the right sound driver for it, sometimes the driver is fit, but it isn't the specific driver for the laptop...u should try to reinstall the very right driver
if its not working, then it is a speaker problem, u can contact the vendor to change

do you have the driver for the notebook, if so reinstall it and if it is still like that you have to change the speaker.

sounds like the speakers are either damaged or have gotten water in them and damage the laptop speakers.

Have you tried with headphones?  Scratchy WITH heaphones. Reinstall driver. If it's NOT scratchy with headphones.  Either your speakers are blown, (which usually doesn't happen), you need to reinstall your sound card drivers, or bad settings.  Double click sound horn. Turn some volumes haflway, or mute sound channels you aren't using. Options Properties will let you show ALL sound properties. Ctrl+S makes the sound properties half size.
ReInstall Drivers: Start - Settings - Control Panel - System - Device Manager, Expand Sound Controllers, Right Click on your sound card, Click Uninstall.  Reboot and reintall.  
Might ask to reinstall automatically.  Thats fine.  Install then reboot.  I prefer to cancel the install until I have rebooted.  But both ways tend to work.  
Hope you don't have to change your speakers.  Need to pull your mobo to get to em. Instructions here pg. 5-55

Try the speakers on another PC with good working sound. This will indicate either a speaker problem or a sound card issue.

If speakers work ok on 2nd pc, then you have a sound card issue on your pc. If speakers are still scratchy on 2nd pc.. check the metal connector end, make sure it is clean and shiny. If there is any rust or other oxidation, clean it off with a very fine grade of sand paper

Are the speakers old? The only thing that can make a random scratchy noise on the speakers as far as I know is a dirty volume knob. Try turning it all the way up and all the way down (with nothing playing) and see if that helps. If it does, blow them out with some compressed air. I'm thinking your issue is probably software / driver related though, does the scratchiness happen in other programs? WinAmp? Windows Media Player? .. if it does, you've narrowed it down to a driver-related issue, go to your sound hardware's manufacturer website and download the latest drivers.
