[alsa-devel] preventing SNDRV_PCM_STATE_XRUN

Hi, all! I have uncontrollable data stream which I need to play through kernel via ALSA snd_pcm_lib_write call. Everything is fine, but once a few seconds I get SNDRV_PCM_STATE_XRUN on stream and thus, -EPIPE. Sound glitches are minor, but annoying.

Is it possible to somehow prevent this from happenning? Is it possible to distinguish if my next chunk of data will fit?

Thanks a lot, S.
