Applied, thanks. Though I suspect that in practice this may actually be
less robust due to the general raciness of the way we configure and
start the streams - I seem to recall the code works this way semi
deliberately so that we always have a rate selected; most systems only
ever use one rate on symmetric audio interfaces.
