Did you check if they are assigned/assignable in gnome-keybinding-properties? I first thought that mute didn't work on mine, but it was just unassigned. And is there still an application listening for them?
If it still doesn't work, you should open a different bug report; this one is about volume keys, and the causes should be different.
