Asus Zenbook sound off and on keys not working

Solution
It is Zen, grasshopper. Sound or no sound, the same it is.

But seriously, can you use the Control Panel to see if the sound device is good and if it is muted? That should serve the same purpose as the shortcut keys. Also, have you tried headphones? There is a small chance that something is wrong with the speakers, but sound is being processed.
