Ubuntu – GNOME Terminal in 18.04: Visual bell only

18.04gnome-terminalterminal-bell

I want to disable the audible terminal bell, and enable the visual terminal bell. I followed the instructions from this answer

$ gsettings get org.gnome.desktop.wm.preferences audible-bell
false

$ gsettings get org.gnome.desktop.wm.preferences visual-bell
true

$ gsettings get org.gnome.desktop.wm.preferences visual-bell-type
'frame-flash'

but I am getting both the audible and visual bells. Likewise, disabling the terminal bell under "Sound" in preferences disables both types.

Ideas?

Apparently, the sound is coming from Ubuntu's alert system. In Ubuntu 18.04, you need to go Setting > Sound > Sound Effects > Alert Volume > Off.

I got this answer from: Turn off error sound on Ubuntu 18.04
