[arch-general] Gnome Sound Events and Settings

What tools are needed in Arch to configure the login and logout sounds for GNOME? When I go into the Volume control, I can only change the alert sounds and that, I can do OK but right now, I cannot get any sounds to work for Login, Logout, e-mail, etc. I've seen references in google for other distros having something called Sound-Preferences or something but I don't see anything like that for Arch. Google also pulled up some forum references to this same question but no answers were ever given. What do other GNOME users do about this in Arch? I'm not aware of how to specify the paths for the right files. Ifound the sound files themselves in /usr/share/sounds but can't figure out where to go from here. Any ideas?
