STM32F7 Discovery - Audio input and output configuration

[Chirag Parmar]

Hello, I am trying to receive input from audio in line and transmit the same signal through audio output on STM32F7 Discovery board. I am generating initialization code using CubeMx, but I need help on which parameters I have to set. I have checked the same questions in the community but no relevant answers have been found. Or else how can I configure WM8994 audio codec IC to generate square wave signal through audio channel. Any relevant answer would be helpful.

Thank You.
