If I hook up AUD_ADCDAT directly to an LED, nothing displays.
From my understanding, AUD_ADCDAT should be a serial input of one bit of a 24 bit audio interface (with 8 bits for the audio data). The ADC converter should convert the audio signal from Line In and pass in bits based on a clock. Hypothetically, the input should blink on and off based on a signal, but I'm just not getting anything. Any ideas? Thanks in advance.Link Copied

An audio codec in many cases need an initialization through it's control interface to start operation. If your question is related to audio codec of DE2 board, yes it needs initialization. You have Verilog examples shpped with the board respectively available from Terasic support pages that operate the codec. Alternatively you can design an interface following the datasheet specifications.
