I am running the AVS Sample app on RaspberryPi3 and it all works good for me. BUT, now I want to configure the audio settings as in I want to send and receive the audio from my custom sound card with port numbers 2,0 to play and 2,1 to capture. I have tried looking for solutions all over but nothing seems to work. Kindly let me know how I could get my setup working. Thanks.
