Anyone know how to prevent the headphone balance creep (found in the Sound Preference pane) on an iBook? I have yet to find a reason why the balance shifts to the left or right. To make matters worse, I often do not even realize this has happened as I listen to Motown and girls groups where the mix can be dodgy to begin with. I was shocked to discover that all Marvelletes songs aren't mixed in the left audio only . . .
