Accessing the other audio input/output ports of EVAL - ADAU1467Z.

So, currently I'm using EVAL-ADAU1467Z board to carry out my audio signal processing project. As per the project specifications, I need multiple inputs to be processed by the board.

So, the board has 4-stereo audio inputs, out of which, one is the main input (SDATA_IN2) and others are the additional serial audio inputs (SDATAIOx). Since, this is a sigma DSP, I have used sigma studio 4.2 (for 64-bit OS) ( to configure and enable different input pins of the board). The main input ( SDATA_IN2) when enabled in sigma studio (by checking the box corresponding to the pin number(which can be read from the board), in the input block of the studio), it correctly enables the on-chip input port, and proper functioning of the audio processing happens, whereas, when I try to use the other inputs(SDATAIOx), and tried to enable the pins corresponding to this port in the studio (by just checking boxes corresponding to these pin numbers on the same block as mentioned in former), the functioning doesn't happen. I referred the data sheet of the eval board and many resource, but couldn't figure out any possible solution.

Infact, same is the issue with output ports as well. (there are 4 output ports, of which 1 is the main one - SDATA_OUT0 and three others- SDATAIOX don't seem to be functioning as expected, when configured similar to input ports, as mentioned above).

I'm really not sure, if I'm doing some thing wrong in studio to enable these ports ( probably missing some additional steps because they are additional ports) or that I'm missing out some connections on the board or if board is not working.

Sir/Ma'am, Kindly reply at the earliest, as until which I have paused my project work.
