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!

Altough the Terasic software examples aren't very instructive, they should be sufficient to see how e. g. the audio codec control interface can be operated. You can consult the DE2_i2sound example. It has a sequence of commands in module clock_500.v that is transmitted through module i2c.v, the I2C-controller that drives the control interface.
