Public bug reported:
Bug occured after upgrading to 11.10. Previously, I was able to plug in
the usb audio (or turn it on, if it was alredy plugged in) and select it
as an output device in the sound settings dialogue (or via pavucontrol).
Now, the device only shows up in the hardware list (listed with 1
output), but no longer in the output list.
USB audio device is a Philips FW-M567 compact stereo system.
If it is any help: apport performed two sound tests. The first one
played correctly on the USB audio device, the second one, however,
played on the Intel sound card, which is why I hit the "not played back
correctly" button.
Another interesting fact: It worked yesterday after I upgraded a few
packages. I didn't change anything after that. Today I turn on my
computer and it's non-functional again.
