How to listen for when track is paused by system

[devskope]

How do I detect when a playing sound is paused/resumed/stopped by the Operating System?

For instance say track.playing() === true and I hit the pause button on my keyboard (or pause from the operating system), does howler emit an event? As far as I know, onpause isn't fired.

I need to toggle certain states when a sound is paused or resumed by the operating system's media controls not only when I explicitly call play(), pause() or stop().

Howler does not pay attention to external/OS audio events, see my comment on #1262 for more information and a possible workaround.
Check #1383 for iOS specifics.
