  ENVY24 has input->output data routing matrix switch. But original ENVY24

  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.
