setting sound preferences in lts.conf or .gconf?

Hi All,
My students use instructional videos that I post on the web.  Sound/Flash is
working beautifully on localapps with Firefox.  The deal is that I need the
sound on the speakers to cut-out when a student plugs in a head
phone--instead the sounds comes out through both.

A work around I've come to is that I can select the 'connector' for
headphones and then the sound ONLY comes out when a headphone is plugged
into the audio jack.  This is great--even better than it is now.  I want to
set this as the default for ALL users.  How do I do that?  I'm thinking
either some lts.conf setting or more likely copy some settings from a .gconf

Any thoughts?
