so I am thinking of sound hardware generating an interrupt at the FIFO having 32-bytes. In your first reply did you mean that periods_min = periods_max =1 would be the setting correponding to my hardware initializations to generate an interrupt after 16 16-bit samples having been transferred? So considering that the FIFO bank is of 64 bytes, what do you think would be the setting for periods_min and periods_max?
