A maximum of 24 cells, with four cells per input in the order INnAL, INnAR INnBL INnBR. For non-muxed inputs the first two cells for that input set the mode for the left and right channel and the second two cells must be 0. For muxed inputs the first two cells for that input set the mode of the left and right A inputs and the second two cells set the mode of the left and right B inputs. Valid mode values are one of the MADERA_INMODE_xxx.
