The first thing to check is on the 2nd page of UsbMode, the View USB.
The audio adapter should be listed under the tree with a 3 or 4 interfaces.
They should all have little black dots to the right.
This indicates that the drivers for that interface are loaded.
The next thing to do is to see that ALSA recognizes the adapter.
Get yourself the ALSA utilities and try alsa_aplay (or however it's named).
alsa_aplay -l will list all devices.
You should have a dummy and your adapter.
