Cure for annoying double click sound on Xubuntu

Not sure how wide spread this is…

On my HP EliteBook 2540p with Xubuntu installed I can hear a very faint double click in the background which is not related to the volume control.

I found the cure ages ago and will put it here for safe-keeping.

The command to run is:

$ echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save

There is a way of making this permanent with adding a configuration setting but for now I’m happy to run this manually after a restart.
