Bug Description

When the center balance is adjusted to the right, scrolling on the volume icon in the panel produces erratic results. The same thing happens when trying to adjust the volume in the sound menu. The volume buttons still function correctly though.

Dragging the handle on the sound menu seems to indicate that it keeps trying to go down instead of following the mouse. Also, when it hits 0, the sound center balance is reset to 0 (right in the center).

Indeed, good catch. The sound menu always manipulated the left channel.

I've attached a branch fixes most of the problem by making it handle channels in the same way that system settings does. Changing the volume to 0 still resets the balance to center, though (same as in system settings).

I'm not sure it should reset the balance to center. Shouldn't it recall the last
balance setting and try to preserve that? FWIW, the system settings also
functions a little weirdly -- if you try to click and drag the volume control
around in the system settings, it starts jumping around like it wants to reduce
its volume instead of following your cursor. Scrolling seems to work as expected
in the system settings though.
