"Mic Bias" is a SUPPLY for both "MIC_IN" and "Mic Jack", so it should look like:
"Mic Jack", "Mic Bias", "MIC_IN", "Mic Bias",Not really. The circuit: MIC_IN <-- capacitor <--> Mic Jack / Mic Bias /
The "Mic Bias" here is really a SGTL5000 internal supply.

DC can not pass the capacitor. So Mic Bias only supply Jack.
