    ENVY24 has input->output data routing matrix switch. But original ENVY24
    matrix control is so complex. So, in this driver, matrix control is
    defined 4 parameters.
  
    1: output DAC channels (include S/PDIF output)
    2: output data classes
       a. direct output from DMA
       b. MIXER output which mixed the DMA outputs and input channels
          (NOTICE: this class is able to set only DAC-1 and S/PDIF output)
       c. direct input from ADC
       d. direct input from S/PDIF
    3: input ADC channel selection(when 2:c. is selected)
    4: left/right reverse
  
    These parameters matrix is bit reduced from original ENVY24 matrix
    pattern(ex. route different ADC input to one DAC). But almost case
    this is enough to use.
