Title:
  [USB-Audio - UAC3553B, playback] No sound at all

Status in pulseaudio package in Ubuntu:
  Invalid

Bug description:
  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.
