Excellent! Thank you! Now, how do I do this without gnome or KDE?

You were absolutely right, the permissions are being magically added by Policy Kit Policykit is controlled by System -> Administration -> Authorizations (or run 'polkit-gnome-authorization') Find the section called "Device-access" from there you will see "Directly access sound devices" Click edit, and change Active Console to no. (Active console means the user who is logged in directly to the system, as opposed to remote log in.)
