Yes, most of such problems come from the inconsistent hw constraints,
and one-shot configuration helps indeed.  But, in this case, it
appears more like an overlooked case to me.

BTW, this reminds me of another question: don't we have a dummy ASoC
driver like snd-dummy?  It would be convenient for a casual API
testing.
