Switched to Mate 16.04 since the clicking noise is present in Lubuntu after installing pulseaudio for Skype to run.
The Noise is only in the left speaker.
Mute fixes it but not acceptable as a fix.
Changing the balance to the right speaker DOES NOT FIX THIS (strange).
Disabling the microphone does not fix this either.

Title:
  clicking noise on acer 131t-c1yf

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My machine is solid state.
  I updated the intel graphics driver
  I update a few days ago via ubuntu udpater

  There is a subtle clicking noise coming from the left speaker.

  The mint 17 usb makes the noise too and then warns me that that the graphics gpu will not be used and then the clicking stops.
  ubuntu makes the noise.
  Lubuntu 16.04 does not make the noise, until I installed pulseaudio.
  before that, it would make the noise if I installed and ran, metacity and or audacity.

  Windows 10 does not make the noise.

  
  I saw some comments on askubuntu.com
  I think it is a conflict with the nouveau driver not loading properly.  This is why the soundcard and graphics affect the problem
  Usually, this bug is caused by alsa automute (removed) and power-save for the sound card.  I was unable to set the settings so that the file changes would "stick"  the kernel keeps overwriting the files even if I mark them as nobody can change.

  I posted the links in the comments

  
  I suspect this is a CherryView Bug.

  
  This bug has been reported on ubuntu forums and ask ubuntu and no responses.
  This bug still exists for Lubuntu 16.04 with the latest kernel 4.6-rc6
  The bios has be downgraded to 1.09 from 1.12 since it did not fix the problem.
