As has already been said, you get what you're given with digital TV 
broadcasts.  However, if you're building yourself, you can modify the 
output volume for your AC-3 (probably used by most, if not all, of your 
digital TV) as at http://cvs.mythtv.org/trac/changeset/15526 .  If 
you're doing AC-3 passthrough, though, you'll have to find a hack for 
your audio receiver (i.e. not Myth).
