After stop, the stream stops and everything looks good(?), but with this message from snd_pcm_writei: -77 (-EBADFD)
You cannot write to a device in the stopped state. This is to be expected.
And you must actually use the return value of snd_pcm_poll_descriptors_count() (there are device types with more than one fd), and you must not look at the returned event flags except with snd_pcm_poll_descriptors_revents().
