Beagolebone black Sound card doesn't recognize on QT code

Hi
I crossed compile the "audiodevices" example on my BBB but when I run the program it seems is not recognized my sound card.
It's shows all the field blank.
Am I have to do something on my BBB or in my QT code to make it happen?
This is my sound card information:

card 0: default [C-Media USB Headphone Set], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Thank You
Iman
