allocate_voice - Allocates a sound card voice for a sample. Allegro game programming library.

       Allocates  a  sound  card  voice  and  prepares  it for playing the specified sample, setting up sensible
       default parameters (maximum volume, centre pan, no change of pitch, no looping). When  you  are  finished
       with  the voice you must free it by calling deallocate_voice() or release_voice().  Allegro can manage up
       to 256 simultaneous voices, but that limit may be lower due to hardware reasons.
