Let me discuss about intercon settings.

Anticipated routes are like below.
 Analog MIC(single ended) -> PGA -> ADC -> SAI
 Analog MIC(differential) -> PGA -> ADC -> SAI
 Digital MIC -> SAI
 SAI -> DAC -> SPOUT
 SAI -> DAC -> LOUT
 LINEIN -> SPOUT

So, I set like below.
Please give us your opinion.
