I have a Dell Inspiron 1300 laptop. As of a few weeks ago, there is a low, constant humming coming from the computer loud-speakers. This sound is also audible when other speakers or headphones are plugged into the same port, so it is not due to the speakers themselves.
I would welcome any possible suggestions as to what might be wrong.

Re: Computer speakers buzzing
Please try moving the laptop to another location, if you have not already tried that, especially if you have any other electromagnetic device nearby (like a transformer, motorized device, machinery, etc...)

some how your mic is conflicting with speakers. Keep your mic away from your speakers..
Hums come from several sources. A light dimmer switch on the wall. Speakers too close to a monitor or other electrical device. Try turning off everything in the room or nearby rooms, one at a time while the hum is audible.
The 2200 uF capacitor in the power supply has gone bad and the humming is a 60 Hz from the rectification of AC to 18 vDC. Either get a new power supply or take apart the power supply and replace the bad cap.
I suspect that what you are hearing is the 60 cps of the mains. If the humming sound is coming the subwoofer itself, then it is possible that you have a defective/leaky capacitor in the power supply section of the subwoofer. In the subwoofer, if the buzzing sound is coming from anywhere else other than the speaker itself, then it is possible that you have a loose transformer again in the power supply. Unless you are comfortable working with testers and soldering irons, I would suggest an electronics technician who should be able to diagnose and fix it for you.
