Need help to configure the audio CODEC (WM8731) on DE1-SoC board through the HPS

Hello Sir,

Thank you for your kindly reply.

Yes, I look that video already and it gave me the general idea how to configure the audio CODEC at beginning.

However, the language that the video used is VHDL and he used FPGA to initialize the chip.

But I have to use the HPS to control the audio CODEC so it doesn't help after.

For the example from github, I look at it before and I couldn't get any information from it since it's really different than the application without OS and using the HWlib (And I have never used linux before so it's even harder for me to completely understand the code) :(
