I got a set of Altec Lansing speakers for use with my iBook. But last night I noticed something really annoying: when the iBook is plugged in to a power source, I get a very loud hum through the speakers. It disappears once I unplug the iBook and have it run off the battery. Is there any chance all I need is a new 1/8" cable for the speakers?

try reversing the ac plug from the ibook to your ac outlet...

try moving cables around; does the hum decrease?

are you plugged into an ac strip? the wall?


experiment with this stuff, see if it helps.

Speakers are very sensitive to irregular voltage. Do you have them connected to a ups/voltage stabilizer?
