Description Robert Roth 2012-01-20 04:00:22 UTC 
Forwarded from Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/918017

Steps to reproduce:

* Open the sound preferences dialog.
* Select output device
* Use the mouse wheel and roll upwards to move balance towards the right.
* Roll downwards and observe that you can only move back to center.

Of course, it should be possible to do the same thing in both directions. 

See http://git.gnome.org/browse/gnome-control-center/tree/panels/sound/gvc-balance-bar.c#n450, where the value is reset to 0 if it goes below 0, while the lower bound of the non-LFE balance types (Left Right, Front Read) is set as -1 (see http://git.gnome.org/browse/gnome-control-center/tree/panels/sound/gvc-balance-bar.c#n272)

Next time please include the original reporter's name, so I don't have to fish it out of launchpad.

    sound: Scrolling on balance only works for right
    
    We used to use 0.0 as the lower bound value but the lower bound
    value is -1.0, which means "all the way to the left" for right-left
    balance.
