My laptop's media keys (volume up/down/mute) are detected via `xev` and `showkey`. I can go into System Settings > Keyboard > Shortcuts and set the volume controls with the media keys. However when I try to use the keys they do not function properly.
I tried setting the keys and rebooting the system but that hasn't worked. Any ideas?
