The microphone mute key is not currently supported in Ubuntu but the fix is fairly straightforward.
First, udev needs to map the micmute key's scancode to a keyname which corresponds to an X key event. This has been fixed[0] in udev upstream. It is possible to make the same change locally, as described here[1]. Second, the key event needs to mute the microphone. This can be accomplished with a small script as described here[1].
