Dell Inspiron 1720 - front media buttons do not control sound

[Kyle Bentley]

I've got a Dell Inspiron 1720. I just upgraded from quantal, and the first thing I've noticed is the media buttons on the front lip of the notebook no longer control the sound level. Mute, Vol up/Down, Play, Prev, Next, Stop. It's odd, because after I rebooted from the upgrade, I raised the volume maybe, 2 clicks, and then it hasn't worked since.
