the ALSA uses the smallest IBL size (i.e. the capture latency) as
default. this is the limitation for the single capture mode.
in the case of full-duplex, you'll get as enough fine resolution of
interrupts as the playback setting because the playback interrupt is
also used to update the capture stream, too. so, in theory, you
should have no problem :)
ciao,
Takashi
