I am using indirect callback mechanism inside ack. I see that ack does not call my indirect callback pointer. Going through the code, I suspect that the appl_ptr is not being incremented and there is no data for the indirect callback to be called. After few acks, I get the indirect callback called. With aplay, I am able to play the wav file. But with flash, there is not data being sent to the driver. Please help me with any clues. Thanks in advance.
