    meet alignment constraints
X - when a setting is chosen for the user due to verification checks, update 
    the setting so that the change is visible to the user.
X - make selected audio red if not same as combo's. instead, I eliminated
    the "update" button.  The currently selected item in the list
    now updates as you change the combo boxes.  Add creates a new entry
    in the list with the current settings. i.e. you start with a duplicate
    of the current selection.
