Yes, you are right.
This setting was miss-settings.
This MICBIAS supplies to external MIC as reference voltage.
So, I think MICBIAS shouldn't appear at this setting.
I show modified settings.
       /* input */
       {"Input Mux", "Analog MIC SingleEnded in", "MIN"},
       {"Input Mux", "Analog MIC Differential in", "MIN"},
       {"Input Mux", "Digital MIC in", "MDIN"},
       {"ADC", "PGA", "Input Mux"},
