ALSA is not a 'HAL' but a 'HEL' (Hardware Exposing Layer). For good
hardware abstraction as much details as possible should be hidden from
the applications. Having 1500+ different functions means that there is
hardly any abstraction left. For this reason ALSA usually needs to be
hidden behind additional libraries (Jack, PulseAudio and dozens of more
to come).
