The function 
load-sound
 converts 
source
 into a loaded sound which can be played by play-sound.
source can be a pathname designator or an array returned by read-sound-file.
owner
 should be a CAPI interface object, or 
nil
 which means that the sound's owner is the current top level interface.
The loaded sound sound will be unloaded (freed) automatically when its owner is destroyed. To create a sound that is never unloaded, pass the screen as the argument owner .
