#**************************************
#this script is for SPDIF-->RXIN0-->DIR-->MainOutput, Record sound from SPDIF to PC through TAS1020

#So
#1, Chose RXIN0 to DIR
#2, Active DIR
#3, chose DIR output as Mainoutput's source.

#Also HW modification
#1, Flying to High Level(3.3V) to make sure U7's output is Hi-Z
#or 2, TAS1020 output logic high on P1.2 I2S enable signal.
