Do you really (normally) need both of them?

Guessing it isn't hard.:-)

You can only open the audio device if it isn't already open.  So if you're
already playing something and need to change some parameter you're
stuck without audioctl.  This doesn't happen very often, and, in fact,
audioctl was introduced much later than audio&sound&mixer.  It was
mostly introduced to be sun compatible.
