I tried to calculate the latency of my system summing up all pd-buffers, 
driver buffers, DACs and ADCs latency (given by the manufactorer) but, 
compared to the measured latency (analog loop-back) I get a difference 
of ~1.5ms (@fs=48kHz). Thus, I wonder what do I wrong and how to 
calculate which latency of a system which predicts the correct 
measurable latency.

Has anybody done a latency calculation and compared it to the measured
