Hi Mark and Peter,

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.
