[alsa-devel] snd_pcm_sw_params_set_start_threshold() functionality

Hello,

snd_pcm_sw_params_set_start_threshold() API description explains, "PCM is automatically started when playback frames available to PCM are >= threshold"

I want to know, whether above pre-buffering(threshold) mechanism is only during the start of playback ? OR Also if my playback device goes to XRUN state, Again next time when i prepare my playback device using snd_pcm_prepare(). Again the prebuffering (threshold) will occur since i have set snd_pcm_sw_params_set_start_threshold() to N periods in software params.

Best Regards, Thanks in advance, Irfan...
