I have a couple comments:
Wouldn't it be better to have the reserved sample slot number given to
al_install_audio, I'd imaging that al_install_audio would reserve a default
number, then a call to reserve_sample_slots would change it for no good
reason. imo, it'd be better to just tell the system how many you want, or -1
(to use the default number) on init.
And this sample id thing, this is what voices in allegro 4 were. And is what I
assume a ALLEGRO_VOICE is. Voice's are the playing instance, SAMPLEs are the
loaded sound.
