release_voice - Releases a sound card voice. Allegro game programming library.

       Releases  a  sound card voice, indicating that you are no longer interested in manipulating it. The sound
       will continue to play, and any resources that it is using will automatically be freed when  it  finishes.
       This  is  essentially  the  same as deallocate_voice(), but it waits for the sound to stop playing before
       taking effect.
