30 * For output, stored in the order of DAC -> ... -> pin,

33 * idx[i] contains the source index number to select on of the widget path[i];
34 * e.g. idx[1] is the index of the DAC (path[0]) selected by path[1] widget
35 * multi[] indicates whether it's a selector widget with multi-connectors
36 * (i.e. the connection selection is mandatory)
37 * vol_ctl and mute_ctl contains the NIDs for the assigned mixers
