Trigger Speaker playback with Animation/Driver

Currently, if you wish for a speaker to play back a sound multiple times, you have to manually add each sound instance separately in the NLA editor. This is very cumbersome when dealing with a very intermittent but frequent sound.

Being able to trigger sound playback in a more dynamic matter would be a welcome addition.

One solution could be to have a speaker play back it's sound whenever a boolean property is enabled. The property could be animated elsewhere or controlled with a driver.
