** Description changed:

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 near from the usb port. The machine is solid state and the ubuntu is running from the sd card The noise happnes with usb live boot too.
+ 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.
-
- Lubuntu installed on top of ubuntu still makes the noise.
- Lubuntu live usb does NOT make the noise.
+ 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 suspect compiz, but ultimately I think it is a kernal problem.
+
+ 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.
- I will be switching to Lubuntu in a few days unless I hear back from you. I am technical and willing to help.
+ 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.
