Feedback From PC Sound System

Check to see how close the speakers are placed to any other electronic equipment,and how close the speakers are to you monitor.
now make sure the speakers line is plugged input is correct.

This is pretty much a lame answer, but it's all I could come up with - make sure that the speakers are 2-3 feet apart and not near any electrical devices (should be fine as long as they're 6-10 inches away from the monitor).

To me it sounds like an enviromental problem, I have a cell phone that couse a Motor Boat sound in my speakers just before it rings. I have seen HVAC product cause problems with Monitor jitter and power Hums. My question is what does this sound like. Is it a High Pitched sound or a Low pitched sound. I may also be where you live, as if you where close to a Radio Tower or Phone Tower

Three possibilities I can think of. 1: try increasing the distance between the speakers themselves. They may be causing interference with each other magnetically. 2: sounds dumb but easy to overlook, is your microphone sitting in front of your speakers and causing feedback? 3: try putting some vibration-absorbing material (like a rubber sheet) under each speaker. It's possible for the speakers to set up sympathetic vibrations in the materials they're sitting on. Hope some of this helps

If you have a PC microphone attached to the sound card, go into your advanced audio properties, and under microphone volume, make sure mute is checked.

If it is unchecked, feedback will result. Basically, what happens is noise picked up by the microphone is transmitted to the speaker, which is picked up by the microphone, and transmitted to the speaker. etc etc ad nauseum.

I had similar prob..it was the MIC..make sure its muted and I am pretty sure that your annoying noice will disappear...hope this helps..:)

There is a known issue with certain sound card/modem combos, especially if they are riser combos or connected with a cd type sound cable. If either situatioon describes your computer, try either disconnecting the sound cable or removing the modem and see if it still happens. Good luck.

First things first, are all of your connections tight? Then look at your speakers quality, are they of good quality and are a descent watts rating for your systems capabilities. If you said yes to the above, then look at you surroundings, do you live near anything that emits a strong electrical pulse or signal such as power lines, a highway (c.b. radios can create strong interference),or maybe a radio, cell phone, or microwave tower. Any of these can create a static dicharge near enough to the frequency rating of your speakers that it can cause your feedback problems.
My only suggestion for you in this is to get a new set of speakers that have a hertz rating at least 5% higher or lower than your current speakers. It should alleviate the problem.

I had a similar problem and it turned out to be a baby monitor adding interference on my amplified speakers. The neigbours only used it when a baby sitter was round, which explained the intermittancy of it. You possibly have a similar problem, perhaps with a nearby CB radio/ cordless phone etc. Using non-amplified speakers or connecting into a hifi seems to work.

I would sugeest that you try these speakers on another computer system. see if they behave better.

It could be the speakers themselves... or the sound card, or the computer system. you need to narrow down what the cause of the problem is.
