X220: Getting the mute button LED to sync with Linux

[the undecided]

The mute button itself does its job, but sometimes the LED is on, but Kubuntu 12.04 has sound turned on. When I press the mute button, that changes and Kubuntu has no sound, but the hardware has. I have to switch it in software and then in hardware to make it on on both sides.

Is there any way to let Kubuntu know what the LED does?
