Volume control alert sound

When using my keyboard’s volume control keys, a sound effect plays alongside a pop-up visual indicator.


How would I edit, or remove the sound that plays here?

Reduce or disable the sound effects in Settings - Sound

My settings look different, and doesn’t seem to have a toggle for alert sounds.

I should also add that I have system volume on 0% anyway, which affects the alert sounds, but doesn’t seem to affect the volume control sound.

You must be on 20.04. Think it’s the drip sound effect. At least on 18.04 it sounds like a drop of water.
