I'm not sure of a good way to handle this without modifying source
code.  But if you are willing to change the source, the way GNOME
usually does "lockdown" features like this is by having a GConf key to
disable a feature, and then you can add a mandatory setting.

If you want to take the "warning" approach, having a program that runs
inside the user session which monitors using the ALSA API (I believe
this is possible), then you can use say zenity or pygtk to pop up a
dialog.
