Deal with a complication when transferring recording method from PP5024: since the FIFO POP is always read until empty, keep track of sample parity instead of always saving the first one in the FIFO upon entering the ISR or else the first of a duplicate that is also the last in the FIFO would get duplicated. Also, give top priority to audio interrupts in all cases.
