Finer volume control in 14.04

In 14.04, the volume slider (controlled by HW switch) seems to move in very large jumps: for instance, from

to

in a single keystroke. Sorry about the tricky screenshot, but that looks like almost a "10%" increase in volume. How can I control volume more finely, i.e. increase in smaller increments?

Go to System Settings and click keyboard.

Click Shortcuts, and custom shortcuts.

Click add and then enter into it the following:

Volume+

amixer -D pulse sset Master 5%+

Click save and then repeat for Volume- (change the 5%+ to 5%-)

Click on disabled, then press the appropriate volume key. It will say Do you want to reassign. Click yes. Do the same for Volume-.

If it is too much of an increase, change it to 2%+ rather than 5%+
