Public bug reported:
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.
