#include <allegro5/allegro_audio.h> bool al_attach_audio_stream_to_voice(ALLEGRO_AUDIO_STREAM *stream, ALLEGRO_VOICE *voice)
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\[aq]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, panning, cannot be changed. At this time, we don\[aq]t recommend attaching audio streams directly to voices. Use a mixer in between.
Returns true on success, false on failure.
