A lot of questions about how to initialize the codec in de2 board

Hi everyone,

I want to configure the CODEC for now. I do a lot of research on Google and I think the way to initialize the CODEC is use the ip core "audio and video config"? I also read the datasheet of the CODEC, the demonstration from the de2 CD. But I am not sure how to use the Qsys to configure the core...also, Can I configure the CODEC with out NIOS ii?

I may ask a lot of questions because I am not familiar with Qsys...

Q1: The frequency of clock input in "a&v config" is depends on what?

Q2: To configure the CODEC, what IP I will need to use?

For now, I just want to confirm I can configure the CODEC, so I want to connect the MICIN and LINEOUT directly.

Many Thanks
