Thank you, I am on KDE Plasma 5.27 (Wayland).

Indeed after switching to GNOME and configuring event sound, I can get the
desired beep.

But by still leaving the config as-is and switching to Plasma or Hyprland, the
sound is gone again.

What Wayland compositor is installed on your system?

The X build ``beeps'' with Xkb or the X protocol, which in fact results
in a beep event being sent to a listening audio server module that plays
a user configurable sound each time it registers such an event.

On Wayland, GDK is responsible for playing the beep sound through the
Wayland protocol. I don't really know how that part works, but it's
unlikely that any failures there can be fixed by us Emacs developers.
