Public bug reported:
About two weeks ago, my computer began to make a recurrent, irregular,
clicking noise every few seconds. It occurs regardless if the computer
is running on battery or electrical outlet. There are no notifications
associated with this clicking noise. Changing the notifications section
in systems does not stop this annoying clicking noise. This noise
continues even when all browsers are shut off. Only turning the volume
off stops the clicking noise. I cannot watch movies or youtube without
hearing this annoying clicking noise.
