I implemented the copy function and immediately transfered the user block data to the hardware.
Correct me if am wrong; .pointer implementation - passes the current buffer pointer. When the .pointer function returns the size of the buffer = user buffer size logically I need to expect the hardware to send an interrupt because buffer is consumed and I should call snd_pcm_period_elapsed after that.
what would happen if i call the snd_pcm_period_elapsed from the pointer function once the buffer is consumed from hardware. Would that be right? This is what i am trying to do

... only if you give more clue what exactly you did.
In general, it implies that an interrupt isn't issued properly at PCM period boundary.
