Question about Altec Lansing 641 Computer Speakers

1 Answer

Scratchy noise? About every ten seconds or so the sound comes in scratchy... I can't tell if this is due to the speakers or the computer messing up. I've checked the cords and they're all hooked up correctly. Do you think re-installing the sound software and drivers would help in this situation? I have no idea what is going on.

    i have no idea how old these speakers are... 5 years maybe? but i'm thinking it might be the sound card, which sucks for me. It makes the noise about every 10-15 seconds on any program that i use, it sometimes even does it at start up. I downloaded all the newest drivers for my sound card and it didn't change anything... the only way i can rule out the speakers is if i get some different ones, plug them in, and see if it does it with those ones. do you know anywhere i could get cheap sound cards or speakers? and will i have to send my computer into Dell to get another sound card installed? this is driving me crazy!

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.

Our Vizio VX42L has an audio problem. The sound is "scratchy." When I change the audio setting completely to the left side speaker, the noise goes away and the sound is fine out of that single...

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!~

Speaker has scrachy sound was it just overpowered, does not make much noise when you push in on the speaker?

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.

My computer speakers have a staticy/scratchy noise coming from them, and it' loud as heck. My speaker just all of a sudden got really noisy. I can only describe it as a static or a scratchy sound. It gets...

Turn off you computer and pull out your sound card if it is external. Then plug it back in the same hole. It may just be loose. If this does not help try another card. If you have a built in sound card try installing updated drivers for it from the manufacturers web site.

The speakers are making a very scratchy noise. They are hooked up to my desktop computer. When first purchased last year, they sounded quite good. Now, they are very scratchy and not on high volume.

Do you by any chance have any other wireless device like a cell phone near the speakers when you hear this?

Any kind of device that has a magnet field will cause scratching sounds on the speakers. I discovered this quite by accident with my old Boost mobile phone.

Scratchy Sound, Major Problem

hi, warranty! get warranty service! you may have faulty sound card in pc. whatever the case, i would get service while you have warranty and the fact it is the same with other set of speakers. are you using same output wire to test second set of speakers? and i am guessing this computer is newer model, so all the drivers should be up to date. check connections again, then get warranty service. have a nice day! hope this helps! glen

Re: scratchy speaker sound quality

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

Scratchy Sound, Major Problem

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

Sound scratchy

Seems to me that the first thing you want to do is find out if your problem comes from the camera speakers/output, or if it records them scratchy. Take one of the "scratchy" cassettes, and play them on another device to see if it transfers bad audio. If it does, then you're worst off offcourse, more of a repair. If it doesn't you can decide you don't need a repair, as long as it does the job. Good luck
