<pre>(alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-22)
do the driver has enough constraints to finalize the parameters when pulseaudio
only set maximum buffer size?
do this mean it support Non integer (e.g.3.7 ) periods per buffer since there
is no constraint
snd_pcm_hw_constraint_integer(runtime, SNDRV_PCM_HW_PARAM_PERIODS);
