unit uSound;
(*
* This unit controls the sounds and music of the game.
* Doesn't really do anything if isSoundEnabled = false and isMusicEnabled = false
*
* There are three basic types of sound controls:
* Music - The background music of the game:
* * will only be played if isMusicEnabled = true
* * can be started, changed, paused and resumed
* Sound - Can be started and stopped
* Looped Sound - Subtype of sound: plays in a loop using a
* "channel", of which the id is returned on start.
* The channel id can be used to stop a specific sound loop.
