Tom & NMGLUGers, I found some control for system sounds in my audio mixer controls, pavucontrol and pulse audio. I use the panel icon for sound, go to audio mixer and then, "Playback" and look for system sounds. I turned mine down a bit, but do not have the problem Tom has with high volume and pitch for system sounds. this would be a start, but not definitive. Also I am now on a desktop, but pavucontrol from the panel does work in laptops, from past experience. Thank you, Ted P

I've got a nice little Acer netbook (maybe twelve years old?) that I use
mainly for car camping and when I want to use a computer at the library.

The problem is that *sometimes* when I use the 'action button' icon from
either the 'main menu' or the 'panel' to suspend, shutdown, etc.; or, if
I have to plugin or unplug the external charger/power supply for
whatever reason, it emits an ear-splitting beep that makes anyone nearby
jump right out of their skin and develop an instant case of PTSD.

Does anyone know how I can disable this?
