** Description changed:

  I use Musical Fidelity V-Link USB Audio. Before 12.04 it has worked
  without any problems. After a fresh install of 12.04 sound seemed to
  work but after the system has been up for some time there is no audio
  output, audio applications occasionally freeze and the audio interfaces
  occasionaly dissapear from the output dialogue in the sound settings in
- the system settings.
+ the system settings. The problem also occurs in a fresh install of
+ 12.10.
