  Line Out audio output rapidly disapears and reappears

Bug description:
  Today my audio became choppy. At first I thought it was a bad audio
  file, but it turned out that everything I play is choppy. Then I
  thought that some process is clogging the CPU or IO, but it wasn't
  that either. After some searching, I opened sound settings and found
  out that Line Out audio output is rapidly disappearing and reappearing
  from the list. I checked the alsamixer and same thing was happening in
  its window.

  I tried to restart the computer, and the problem disappeared only to
  come back again after a short time. I still have my old 14.04
  installation, I rebooted to that and everything worked as it should.

  I have never seen anything like this, I have no clue what is happening
  and I have no idea what to check. dmesg output showed nothing related
  to sound. Since it is very unusual, I have attached a video of what is
  going on.
