What's the correct approach in > handling this corner case? We could add a sanity check in the function, of course. But relying on it doesn't sound nice. At least, the caller should be surely at the certain state that the buffer has been set up, i.e. checking whether snd_pcm_state() returns SETUP or better condition.
