Some jacks are designed to have a connection internally between
two pins, until something is plugged in. Grab an unused male jack,
check continuity (do you have signal between pins), then insert
the jack and test again. If you find two pins that ARE connected
when no jack is in and are NOT connected when the jack IS in,
that's what you're looking for. That way, you can wire it so
your audio goes to the internal speaker normally, unless you
have headphones plugged in. And you gotta use a jack that's not
connected to anything (can't use your headphones) when checking
for continuity.
