I am trying to use my device as a sound card and enabled CONFIG_USB_AUDIO.

That configuration is for the host driver, not for the gadget driver.

I could get my device to be detected as a sound card

Then you have correctly enabled CONFIG_USB_F_UAC1.

However I don't know what kind of device node should be added in the machine file?

As far as I can see, none. See Documentation/usb/gadget-testing.txt.
