Volume Control needs to be adjusted

I am using pure rasperry pi and the volume control is not adjusted the way one would expect. Changing the volume to 90% nearly reduces the volume to a level I would expect at 70% - lowering the volume down to 70% the level is what i would expect at 30%.

This leads to the problem that effectively volume level is regulated only between 80-100% of the volume control.

This seems to be a bug regarding the adjustment of the volume level widget.
