latley just noticed the sound output being really noisy, Seems to react to the movements of the mouse & all general movement around the computer.

I had the same problem with a 9500 a while back but can't remeber how i solved it. it's really anoying & i have to mute the volume when not listing to sound files.

Anyone else noticed this as a problem too?

I've tried moving the computer, Changing Audio cables, disconecting external devices (keyboard, mouse) & Deleting sound & system prefs.

Still no luck! Faulty PSU maybe?
