Hello, i have problem with audio processing using DE2 board. I am doing my project using VHDL and combine them all together using block diagram. I've set the WM8731 configuration not to enable bypass, but i still get the clean sound from my input(i m using a guitar).I've try a lot of design but it still give me the same result. At once, i try to delete pin AUD_ADCDAT and AUD_DACDAT, the i try to run it,strangely, it still give me sound from guitar. do u have any opinion about this matter?
