ALSA is now used in different ways. PulseAudio sets a timer and relies on snd_pcm_avail() to query how many samples it can write to the ring buffer, the notion of period isn't used at all. I think we could use additional information in the way the hw_ptr position is reported, namely hints on how precise this information is and the granularity of the updates. - Pierre _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
