Also this doesn't make much sense:
{"Input Mux", "Analog MIC in", "MICBIAS"},{"Input Mux", "Digital MIC in", "MICBIAS"},You have mux, but both possible settings of the mux connect to the same source, which pretty much makes the mux useless.
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"},
The middle part(the control) of the path must either be a control attached to the mixer on the left side(the sink) or a element of the mux's enum if a mux is on the left side. If the left side is neither a mixer or a mux the middle part is ignored.
The other problem probably is that you have one mux which lets you switch between single-ended analog input, differential analog input and digital input. The first two options are routed through PGA and ADC the later not.
