[alsa-devel] Requiring the same sample rate for playback and record?

In my driver, how do I tell ALSA that the sample rate for playback must be the
same as for capture?

I know I can have my driver remember the sample rate for the first stream open,
and then if the second stream doesn't specify the same sample rate, it can
reject it, but this is inelegant.  I'm hoping there's a more straightforward way.
