Correct sound balance 1.0

Sound balance is a quick fix to a lesser known bug in OS X where changing the system volume rapidly using the keyboard controls causes the systems sound balance to shift randomly.

I often spent hours wondering what was wrong with my speakers as one always sounded louder than the other... heres the fix.

An example is when Im listening to a tune and enjoy a part of the song so crank up the volume quickly using the keyboard and then the tune becomes boring so I turn it down quickly using the keyboard. Others disagree but often when I do this the sound balance changes randomly.
