       al_set_default_mixer - Allegro 5 API
SYNOPSIS
              #include <allegro5/allegro_audio.h>
              bool al_set_default_mixer(ALLEGRO_MIXER *mixer)
DESCRIPTION
       Sets  the default mixer.  All samples started with al_play_sample(3alleg5) will be stopped and all sample
       instances returned by al_lock_sample_id(3alleg5) will be invalidated.  If you are using your  own  mixer,
       this should be called before al_reserve_samples(3alleg5).
       Returns true on success, false on error.
