[alsa-devel] resetting an audio device?

Hi guys,

I got my alsa player code to work. Now I need to figure out how to reset the audio device? I don't want to close the device, just recycle it. Any pointers?

Also, where are the documents for all of those helper subroutes? Like snd_pcm_hw_params_get_period_time, snd_pcm_hw_params_any, etc.

Thanks for your time.
