Set snd_pcm_hardware.period_bytes_min to 16 or is that 16 * samplesize?

This value is measured in bytes.

snd_pcm_hw_constraint_step(runtime, 0, SNDRV_PCM_HW_PARAM_PERIOD_BYTES, 16);

This parameter is measured in frames.

Isn't SNDRV_PCM_HW_PARAM_PERIOD_SIZE measured in frames, and SNDRV_PCM_HW_PARAM_PERIOD_BYTES in bytes?
