The speaker is not the problem as I plug it in my unibody Macbook and the problem gone away. Also, it didn't hum when I hooked it up with my Core 2 Quad desktop. All my equipment is protect with a UPS. I did some research and people was suggesting it is a ground problem. I bought an very expensive ebtech ground filter. Nothing helps so far. Has anybody got any ideas? tx
I've never felt the need for ext. speakers on any of my Macs!!

The inbuilt ones sound great to me - and I do like good audio

Live each day as it comes - it may be your last !?
