[PLUG] USB audio recognized but not working

[Eric Lucas via plug <plug@lists.phillylinux.org>]

I'm installing kubuntu 18.04 on my laptop. 

I have a USB audio device, a Behringer UCA202 connected to my external speakers. 

In the previous (Fedora 26) incarnation it just worked. 

Now it fails. 

The device appears to be recognized: (from dmesg...)

[ 9703.823862] usb 1-3: new full-speed USB device number 10 using xhci_hcd

...however all audio comes from the laptop speakers instead of through the USB audio (preferred!)

I notice it says "input" but there is no "output". 

What am I missing here?

Thanks

Eric
