al_attach_audio_stream_to_voice - Allegro 5 API

       Attaches  an  audio  stream  to  a  voice.  The same rules as al_attach_sample_instance_to_voice(3alleg5)
       apply.  This may fail if the driver can’t create a voice with the buffer count and buffer size the stream
       uses.

       An audio stream attached directly to a voice  has  a  number  of  limitations:  The  audio  stream  plays
       immediately  and  cannot be stopped.  The stream position, speed, gain and panning cannot be changed.  At
       this time, we don’t recommend attaching audio streams directly to voices.  Use a mixer inbetween.

       Returns true on success, false on failure.
