Confusingly, snd_pcm_hw_params_free() and snd_pcm_hw_free() are different.
The former is just to free the malloced snd_pcm_hw_params struct while the latter corresponds to snd_xxx_hw_free().

Is there any flags in substream which can indicate snd_xxx_hw_params() was called at first time since snd_xxx_hw_params() were called many times during OSS emulation (probing the supported rates , channels , .... ) ?
