TLV320ADC3101: pps flow - split block issue

Part Number: TLV320ADC3101

Dear expert, 

I am using the pps flow to develop the algorithm flow as depicted in the drawing, 

I use the single mono channel as the input and use the split block to copy this signal and send it to the left and right output. both the left and right out put has the same signal output when I use it the TLV320EVM board. the display in the Audacity software shows correct both channel.  but when I generate the headfile and send to MCU with my own board, I can only get the correct out from the left channel, the value in the right-channel is not correct, with very low value, seems like it is noise.

The way I use the flow is to generate a head file and in the MCU, using the program to change the register value into the value as in the head file.

could you kindly tell me what is the reason for that? 

1. is the split function just a copy of the incoming  signal

2. is there any specialized register should I changed when using the split block.

3. could you pls check with the headfile and check whether some wrong setting for the register setting?
