Out of the blue, my beloved SoundSticks have freaked out. Ear-shattering feedback has made them impossible to use. Seems to be affected by movement of the pale green mini plug in my iBook. Comes and goes mysteriously but frequently. Are my SoundSticks possessed?!
Same problem...at the beginning i just pull the jack and put back from my cumputer and it was gone, but now after 2 weeks i can heard the hum very strong, any idea? don't say you can through to the bin!!!!! please help!!!!!! thanks

First you need to determine where the problem is. Try connecting your speakers
to another audio source such as a portable CD player. If you receive the proper
sonic results, this will tell you that the problem is in the computer and/or
soundcard setup. In this case there are many things to try. 1. Interference may
be causing the distortion. Please check all surrounding electrical objects and
place the speakers away from the problem object. 2. Ensure that the speaker
input jack is pushed all the way into the appropriate jack. Check all the
connections and secure them. 3. The volume on your soundcard may be set too
high. Decrease the volume in your volume control panel. Also check the volume
and tone controls on the speaker. 4. Sound card or audio source material may
cause a problem. *note* the quality of the audio source is also a factor (i.e.
bad recording). The compatibility of your CD/DVD rom drive, soundcard and
software will contribute to the quality of your sound.
Check the grounding on the power supply. That eliminates almost all "droning" and "buzzing" feebacks. Try detaching all externally powered accessories to see whether one might be responsible (external hard drives are traditionally the worst, but I got a USB hub once which had a faulty wiring - the droning was the first warning of impending doom).
If this does not work, you can sometimes get rid of some interferences (but usually at higher frequencies than dronings - anyway, it's worth a try) by clamping a ferrite load around the mains wire and/or the DC output wire. Many USB and audio cables will have clip-on ferrite loads which you can unlatch using a thumbnail or a pencil knife, and reuse for your own.
If it's the AC adapter, you might be able to secure a compatible AC adapter that will buzz less. I've found some recovered printer AC supplies from Hewlett Packard to be quite silent electrically (check voltage, wattage and polarity carefully though).
Unplug the minijack from computer to hear if it still hums. If not test speakers at another computer. if it works fine on other computer the sounncard is generating hum noise. Common problem is usually the earthing cable inside the minjack that is touching L or R speakerwire due to bending of cable and breaking off insulation. If youre up to it cut off minijack if its moulde and resolder a new one on.
