Hi,
I'm trying to develop an alsa driver for an embedded audio card which includes some hardware codec. I would like to use alsa for handling the whole audio card : mixer, pcm and hardware codec. Right now, I have no major issue with the mixer and the pcm stream but several question about how alsa behaves with an encoded audio stream. Several audio format are already defined in the sndrv_pcm_format enum but i can't find any details about how the period size and the elapse notification is handled with encoded data . Where can i find some details ? is there any alsa sound cards driver which already manage encoded audio stream ?
Regards,
Vincent
