Greetings all have been a lurker here for awhile and finally took the plunge 2 days ago and bought a new 12" iBook. Love it so far, this forum helped sell me on the idea of getting it. Love the Display spanning hack that was talked about. Now the question. If I change the balance on the sound all the way to the left I get a real high pitched version of what I am playing, if I change the balance all the way to the right I get a muffeled mid range version of what I am playing. Is this a defect or did they mean to do it this way ?
