When I turn on the theater system, There is a long delay before the sound comes on. System includes Sony LCD, Onkyo 601, Sony DVD. DirecTV/Antenna (HDTV) audio through receiver obviously but video to TV directly to take advantage of DVI cable. . . With DVD, sound comes up quickly but with TV programming, two red lights are blinking like the receiver is searching for a source. It typically takes 30-45 seconds for what is then normal sound. I think it is set to decide automatically the type of sound output?? Do I need to give it a specific setting for TV programming all the time?? I know it's a rookie question. Please help.
