Set emacs up to ring the bell using an external program, since the normal beep/bell/ding doesn't seem to work any more.

tkb-bell.el

(defvar tkb-beep-sound "/usr/share/sounds/freedesktop/stereo/bell.oga")
(defvar tkb-beep-program "ogg123")

(defun tkb-bell ()
  (interactive)
  (start-process "Beep" nil tkb-beep-program
                 tkb-beep-sound))

(setq ring-bell-function #'tkb-bell)

(unless (file-exists-p tkb-beep-sound)
  (yes-or-no-p (format "Error: tkb-beep-sound is set to \"%s\", which does \
not  exist!\nUnderstand? "
           tkb-beep-sound)))
(let ((path (split-string (getenv "PATH") ":")))
  (unless (file-installed-p tkb-beep-program path)
    (yes-or-no-p (format "Error: tkb-beep-sound is set to \"%s\", which does \
not exist!\nUnderstand? "
             tkb-beep-program))))

This seems to be a Wayland problem, so a more complete solution would be something like this.
