resetting an audio device?

resetting an audio device?

[william estrada]

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.

When the device is not running (i.e., after calling snd_pcm_drop()),
call snd_pcm_hw_free() to free the configuration; then you can set a
new configuration with the snd_pcm_hw_params* functions.

I don't need item one, it works now.

But I would like to see the better API docs.
