The period_bytes_min parameter made no sense at all, as it didn't

Does the device really work with less than 64 bytes period size?
I meant not in theory but in practice.
somewhat predictably, not.
Without any value set,
dumb applications may try to set 4 bytes for period size,
the "try to" is key here. it will fail, because the frame-based
constraint will prevent it from doing so.
alsa's constraint system is really quite impressive, probably the
technically most interesting part of the whole. :-)
