xrun and snd_pcm_prepare.

[Shaju Abraham <shaju@multitech.co.in>]

Hi,
    In aplay utility to playback music, we see that if the return value
is -EPIPE, a function xrun() is called. This function does nothing more
than snd_pcm_prepare(handle).  What is the meaning of receiving a -EPIPE
return value to a application? and, Why cannot this be done at the
driver level itself? say in pcm_native.c .

Is it ok if this snd_pcm_prepare is called from pcm_native.c instead of
returning -EPIPE to the application?
