Although this can seem at first to be a physical problem with the breakout box and may lead you to think that you need to replace the unit, this may not be the case.  These symptoms can be caused by settings in the Delta Console changing the function of the channels by enabling the Bass Management options.  This option is only available in newer versions of the driver install, so will not affect older drivers.

To resolve this problem go to the Bass Management tab in the Delta Control Panel and make sure that the General Settings tick box is NOT ticked. (See Pic)
