Volume up key loses functionality (XF86AudioRaiseVolume)

I'm running FC20 and XFCE 4.10. Using the handy, easy-to-use XFCE keymap, I've assigned XF86RaiseVolume and XF86LowerVolume to pactl -- set-sink volume 1 +5% and -5% accordingly. (That's xfce4-keyboard-settings provided by xfce4-settings-4.10.1-3.fc20.x86_64.)

Everything was working great until a few weeks ago when my Volume Up key stopped working. Volume Down correctly passes the command to pactl, but Volume Up wouldn't do anything. A reboot cured it.

It's stopped working again after only two or three days, which is very annoying. I discovered while researching stuff for this question that, if I run Gnome's system-config-keyboard, and accept the US/English layout I already have selected, the Volume Up key works again!

The keyboard is a USB Microsoft Natural Ergonomic Keyboard 4000.

An evtest shows that the computer is correctly receiving the input, but not acting on it. Any ideas what I should be looking for?
