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.

Re: Scratchy noise?

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.

Scratchy sounding volume controls?

If you have a scratchy sounding volume control or your channels cut in and out when adjusting the volume you are most likely suffering from a dirty potentiometer (volume knob) Fully disassemble your DTT2500 unit and liberally spray electronics cleaner in every party of the volume knob (and the other knobs as well). Let fully dry before reassembling.

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.

Suddenly my speaker volume is low and scratchy

Congrats, you yourself is a good troubleshooter. Just pinpointed your problem. What you just diagnoist can be easilly checked just by taking other good known speaker. If that works your speaker is short check for audio output wires. If not your card needs replacement. If need further clarifications just comment.

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

Scratchy loud noise when volume dial is turned

It means that the volume pot is dirty.You need to find a way to get some WD-40 into the pot.This usualy requires that you take the access to the inside off and spray right inside the pot.Once you do this move the volume dial from min to max a few times and it should fix it.

try going to control panel, the system icon, hardware tab, divice manager, check to see if your sound card does not have a yellow ! icon next to it, if it does try right click, go to properties, and reinstalling it, it does help if the computer is hooked to the internet so it can find it automaticly over the internet.

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
