Hi developer,

When I use arecord command, then there was "overrun" occue every time once trigger the audio recording. I have no clue of alsa driver when and how handler xrun. In other words, how to understand function snd_pcm_update_hw_ptr0 in pcm_lib.c. Please enlighten me on this issue. Thanks a lot in advance.
