Manually 'type' the 568.2 to 7.1 AAA and the L/R digital outputs will be active and volume controlled. You may experience 'clicking' on the Lavry when the DSP mode changes during the trailers on a DVD in which case try setting the 'level' for the L/R channels below zero, eg. -3 (Ronomy is the best person to give you advice on that).
