BX3105 Audio SINK and SOURCE on Development Board

Hi. I have 2 BX3105 Development boards and want to provide audio input on one board to be received and output by the other board. I am told there are scripting examples to quickly set up each end but I can’t seem to find them. Can someone provide a setup for both an audio SINK and an audio SOURCE, ideally using the BX3105 Development board? Thank you!
