this is a detail that should not be apparent in an API that aims at
abstracting an audio system. the same comment applies to stuff like:
#define SOUNDBOX_PORT_PROPERTY_BUFFER_SHAPE /* interleaved, noninterleaved,
complex */
if a hardware PCM "component" exports this kind of stuff, we're in no
better shape than using ALSA when it comes to abstraction.

what is supposed to call this? when is it supposed to be called? when
a connection is being attempted?
