I am tesing my alsa driver for an arm based board. aplay works well when it
is used in blocking mode, but I see
underruns when I switch to non-blocking mode. What could be the reason?

I have tried to remove all latencies in driver by using minimal locking etc,
but it doesn't seem to make any difference.
Also, the audio quality degenerates gradually in non-blocking mode.
