Hi I hope this is the right forum for a post about a problem I have with set of Klipsch Pro Media 2.1 Computer Speakers. (Link to product)  http://www.klipsch.com/products/klipsch-promedia-2-1-computer-speakers#promedia-2-1

 

 

The problem is that as I turn the main volume knob the audio will switch from left to right channels. When I stop turning the knob the I get some variation of channels working. It may be only the left or right channel working by itself. Or left and right channels both work but one side is much quieter than the other. And sometimes it may periodically go back and forth between whether both channels produce sound or just one; the audio on the other drops out and comes back sometimes.

 

Does anyone have any idea whats going on with my speakers. All help is appreciated.

This sounds to me like the typical symptoms of a defective dual gang volume potentiometer. If so the only permanent cure is to replace the potentiometer (or the speakers). Switch contact cleaner may help temporarily - if you can access the rear of the potentiometer safely & if it has any apertures to spray into.

Alternatively see if you can find one position (at high volume) where the speakers are working OK & then use ONLY the computer volume control for ALL future adjustments - this may allow you to continue using your speakers for a while.

If I turn up the knob alot I think I can get both channels to work but then you can hear the static more which is a bit annoying. I'll have to research those methods to see which one I'd wanna try. Thanks for the help!
