If you set it via amixer then use alsactl store that should
add it to the default. It probably also needs to be filed as
a bug somewhere (probably against Alsa) if the control
can't be made to show up in the gnome volume control
through the preferences menu (I had a similar problem
a while back with digital capture not showing up).
