Constant speaker clicking in ubuntu

[x-shaney-x]

As I use the laptop I get a clicking sound coming from the speaker.
It is one short click every 2-3 seconds and just won't go away.

Altering the volume makes no different to the volume of the clicking.
It happens whether I am running applications or with an empty desktop.
Only noticed it happening today and there were a few updates yesterday, amongst them a kernel update.
This only happens when running ubuntu, no clicking in Windows 7 or Chromium OS.

Laptop is an Acer Aspire 5742G
According to lshw:

             description: Audio device

I'm at my wits end with this!

Same here. Just updated to Version 20.0.1132.47

Version of what? Looks like a Chrome version, which isn't the problem.

Tried booting with the previous kernel (3.2.0-25) and not getting the clicking so looks like it was the kernel upgrade.

Spoke too soon. The clicking started up again

This was happening to me up until yesterday and had been happening for a few days.

I did a clean install last night, and did today's updates. All seems well.

Well I had been thinking of doing a fresh install to put 64-bit back on (tried 32-bit this time around to see if there was any difference).
