I want to make something like an audio player with a CyclonII development kit ( EP2C20F484C7 FPGA). For that i need do configure a wm9731 audio codec. My problem is that i know a lot of theory, but i have a stronk lack of practice, so i don't really know what to do, and if i can configure it with Quartus II. I can't really figure out what the line in connection si for. I think i need to put the audio signal in the micin connection in the audio codec, to send it to the sram memory using the fpga, and after that to send it back to the codec from the memory using the fpga, and finnaly to the line out connection. Am I right?
