Qt App couldn't detect my usb sound card
I Run the Audiodevices example on my BBB but it seems the app couldn't detect my USB sound card.
The program shows noting in all field.
I'm wondering am I have to do something to export my USB sound card to my QT app like the
for adding Touch screen to my QT APP, Or it should be detect it automatically?
This is the result of aplay -l
card 0: default [C-Media USB Headphone Set], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0
Any help will appreciated
