I've noticed there's no sound coming out of my DDX 7019 everytime it's cold (30 F and below). It boots up starts playing whatever it played before. I can see the time of the tracks going and everything but no sound at all. The only fix is to press Standby and then back to the Menu and the source(DVD, USB, IPOD etc.) when it's too cold (10F) I even had to reset the unit to get the sound back WTF?????? When it's warm (32F and up) no problem at all? Seems abnormal. What it might be?
