/*===============================================================================================
MultipleSoundCard Example
Copyright (c), Firelight Technologies Pty, Ltd 2004-2016.
This example shows how to play sounds on 2 different sound cards from the same application.
It creates 2 FMOD::System objects, selects a different sound device for each, then allows
the user to play 1 sound on 1 soundcard and another sound on another soundcard.
Note that sounds created on device A cannot be played on device B and vice versa.
You will have to each sound separately for each sound card. Device A might load the sound
into its own memory so obviously device B wouldnt be able to play it.
