We'll need to update the firmware, this requires Internet access but only takes 15 minutes or so. You might want to run sudo apt-get update first if you haven't lately. Then run the following commands in order:
sudo apt-get update
sudo apt-get upgrade
sudo reboot
Now you can go down to the update alsa module options section
