The same thing happened to me where my top row keys wouldn't function, including the volume and brightness keys. I tried the shut down process, and it didn't work. When I checked settings and went to keyboard, I realized I had pressed "Treat top-row keys as function keys." After I unchecked it, my volume keys worked again.
