Latitude E6540 volume indicator

When I press the volume buttons on the laptop, it doesn't show what volume level it's at; I have to right-click Windows 7's speaker icon at the bottom right to see it or adjust it better, as using Dell's buttons increment by 2, meaning it takes forever to turn the volume up and down. Holding the button down doesn't help much.

Is there a way to get a level indication on the screen, and to maybe make the increments larger, like 5 or 10%?
