"To get rid of the shutdown beep (and perhaps making that last step redundent) you should blacklist the pc speaker:
In a terminal type "gksu gedit /etc/modprobe.d/blacklist.conf"
=>This will open gedit, go to the last line in the file.
Type "blacklist pcspkr" without quotes onto a blank line at the end of this file and then save and close gedit."

"blacklist pcspkr" did not work for me. I still had the beep at shutdown.
Instead, I did the following:
sudo modprobe -r pcspkr

This fixed it. Seems to work across reboots, too.
