Can not hear audio in ADV7511 reference design

I use the xilinx board ZC702 to run your reference disign about ADV7511 which provide from your website:

"ADV7511 XILINX EVALUATION BOARDS REFERENCE DESIGN"

It suppose can display an image and play a sound.

After runing the download.bat, I can see the image on the monitor but could not hear any sound.

I also tried to run the HDL reference design and software reference design on xilinx tool SDK, the result is same.

I'v already check the monitor is working well.

Do you have any suggestion for this problem?

 

Here are the messages shows on the console after running:
