I was the same problem.
I don't do much things to get it work again.
I think it was only plug my headphone and unplug it for the sound back on.
Ps.: I've install "gnome-shell 3" and get to use that before i mad the procedure describe in up text.
I hope this information is enough to solve the problem.
