Ask about the DE2 Audio Codec.

I set-up everything as in the manual, and use the reference design to play music(48KHZ,wav). But why there is much noise along with the music from the headset? Thanks for help!

Some confusion may come from the audio codec capabilities to support different modes. I suggest to look at the slave mode configuration shown in Fig. 6 + 7 in the datasheet. It's best suited for FPGA operation and rather straightforward. The codec has to be setup to the respective mode through control interface before operation.
