Description: 通过 fpga 控制音频编解码芯片 wm8731 产生一个 1khz 的正弦波，接上 AC620
板上的耳机接口，试听此正弦波。（注意，声音比较大，如果为了保险，可以使用
带音量控制的音响，也可以用示波器观察）。(The audio codec chip wm8731 is controlled by FPGA to produce a 1 kHz sinusoidal wave connected with AC620
Listen to this sinusoidal wave with the earphone interface on the board. (Note that the voice is louder. For insurance purposes, you can use it.
Audio with volume control can also be observed by an oscilloscope.)
