For non-muxed inputs the first two cells 39 for that input set the mode for the left and right channel 40 and the second two cells must be 0. For muxed inputs the 41 first two cells for that input set the mode of the left and 42 right A inputs and the second two cells set the mode of the 43 left and right B inputs. Valid mode values are one of the 44 MADERA_INMODE_xxx.
