gsettings schema for sound?

[Dean Hunter <deanhunter comcast net>]

By trial and error I have found the gsettings schema and keys for a
number of items I would like to configure in an Anaconda Kickstart post
script: 

  gsettings set org.gnome.desktop.background picture-options 'zoom'
  gsettings set org.gnome.desktop.background picture-uri
'file:///usr/share/backgrounds/gnome/FootFall.png'
  gsettings set org.gnome.desktop.background primary-color '#ffffff'
  gsettings set org.gnome.desktop.background secondary-color '#000000'
  gsettings set org.gnome.desktop.interface clock-show-date true
  gsettings set org.gnome.desktop.screensaver lock-enabled false
  gsettings set org.gnome.desktop.sound event-sounds false
  gsettings set org.gnome.gedit.preferences.editor create-backup-copy
false
  gsettings set org.gnome.gedit.preferences.editor wrap-mode 'none'
  gsettings set org.gnome.nautilus.preferences default-folder-viewer
'list-view'
  gsettings set org.gnome.nautilus.preferences sort-directories-first
true
  gsettings set org.gnome.shell always-show-log-out true
  gsettings set org.gnome.shell favorite-apps "['firefox.desktop',
'nautilus.desktop', 'gedit.desktop', 'gnome-terminal.desktop',
'virt-manager.desktop']"

But I have been unable to identify the schema and keys for the values
set by the Sound applet of the Control Center in Gnome 3.6. Is there a
cross-reference between the applets and schemas that I should consult?
