I have just replaced a Playbar with Arc. The Playbar was connected via the optical cable, and the new Arc is via ARC from TV. Previously the sound would come from instantly from Playbar as soon as picture appeared on TV. When I turn the TV on, there seems to be a 5 second delay after the picture first appears before green light flashes on the Arc and sound is heard from Arc, ie there is no sound for 5 seconds after TV Picture is visible when turning TV on.
I was wondering if this is normal for ARC connected devices vs Optical? Is there any adjustments on the Arc that can be done to improve the 5 second delay?
