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.
