I'm used to being able to hold down shift while pressing volume up/down to hear a click noise so that I can tell how loud the volume is. Now on the Macbook Pro with the Touch Bar (macOS Sierra), that doesn't work.
Is there a simple way like this to test the volume level while changing it, or did Apple decide to remove that completely?

Thanks to the answer by @nickcrabtree, the checkbox "Play feedback when volume is changed" in Sound preferences should enable/disable the need to hold shift for the sound feedback to play.
However...when I check it, the sound feedback is played (though if I hold shift it still plays). When I uncheck it, the sound feedback doesn't play even when holding shift. However, when I plug in an external mac keyboard and use its volume keys, it behaves as expected. Seems like a bug to me.

In System Preferences, in the Sound section, under "Sound Effects" there is an option in macOS Sierra "Play feedback when volume is changed".
If this option is not checked, then the behaviour described in the question occurs (you hear the feedback when the shift key is pressed).
If this option is checked, then sound feedback is played normally, and is suppressed when the shift key is pressed. This is the default behaviour.
In order to return to the behaviour you are used to, you need to deselect this check box.
