The most recent version of Emacs doesn't recognize the XF86AudioLowerVolume key. I use "C-h k" to check this in "emacs -Q". When I press XF86AudioLowerVolume once, no information is displayed. However, If I press XF86AudioLowerVolume twice, "C-h k" indicates that I pressed "C-g".

I believe that this behavior is introduced in emacs-30, because this key works fine in the released emacs 29.1.

To reproduce, simply press the XF86AudioLowerVolume key  in "emacs -Q".
