     Make sure this is not turned on while any other source is connected to input 1/2.
     It might damage the source and/or the maya44 card.

     This is not supported by the ESI windows driver.

+Digitial output selectors
     These switches allow a direct digital routing from the ADCs to the DACs.
     Each switch determines where the digital input data to one of the DACs comes from.
     They are not supported by the ESI windows driver.
     For normal operation, they should all be set to "PCM out".

-H/W 1: Output source channel 2
-H/W 2: Output source channel 3

-H/W 4 ... H/W 9: unknown function, left in to enable testing.
     Possibly some of these control S/PDIF output(s).
     If these turn out to be unused, they will go away in later driver versions.
 
 Selectable values for each of the digital output selectors are:
-   "PCM out" -> DAC output of the corresponding channel (default setting)
-   "Input 1"...
-   "Input 4" -> direct routing from ADC output of the selected input channel
