I don't see a problem here. If transfer is stopped, the pcm handle is
not initialized for I/O transactions, thus upper layers return these
Your application should check snd_pcm_state() in case of error and look if
stream is inactive (back in SND_PCM_STATE_SETUP), because your application
invoked the drop() call.
