Hi thanks a lot for hint provided by you.
It works fine now.
What threshold value is better boundary value OR alsa buffer size value 
for good performance ?

Observation :
I do lot of console operation purposely to get ALSA underrun.
After above implementation i do not see any UNDERRUN.

Is there any way we can avoid above jerks ?

xfer_align function is depreciated.



Thanks and regards
