Denon AVR-5700 Song beginnings cut off on digital input

[Yaminom]

Hi, Folks.

I've got a Denon AVR-5700 that has always had an annoying problem. I'm hoping someone here can help me with it.

The problem crops up when I use the optical digital inputs. No matter what the source (Sony CD player, Denon DVD-2200, Apple Airport Express), the first second of music is always cut off. It seems as though the receiver doesn't activate its input circuitry until it sees a signal coming in, and thus doesn't start processing until one seconds into the track.

It only happens on the first track of a CD, but when using the Airport Express it seems to happen with every song. That's why I'm only just now beginning to find it intolerable, though I've had the receiver for a couple of years.

There are three choices for selecting the digital input type: Digital Auto, Digital, and PCM. It happens no matter which of these I select.

I haven't seen anything about this in any forum, though maybe I'm just not using the right search terms.

Any ideas, anyone? I'd appreciate the help.
