I can mute and then amplify sounds globally, and this works
well, but results in some of the sounds going back to 100% volume
when they were originally just beginning to fade out (that is, they
shouldn't be going back to 100% volume, but lower).
Therefore, I need to pause and then resume these sounds
globally, rather than mute them.
if you want to pause and restart the sound you should just
use the stop() (storing the position property) and start() (using
the stored position/1000 in the offset parameter) methods of the
