How do you specify a callback for rb->pcm_play_data()?

    The prototype for the callback function is as follows:

    static void my_audio_callback(const void **start, size_t *size);
    

    *start should be set to point to the region of memory where your PCM data is stored (16-bit signed integers), and *size should be the size of this region.

    Once you've written your callback, call rb->pcm_play_data(), and enjoy the music!

    rb->pcm_play_data(my_audio_callback, NULL, NULL, 0);
