Hoping someone can give me some insight or advice. I have a Marantz SR6015 paired up to an XBOX series S. Video and audio are sent to it using a high speed HDMI and passed through to an EPSON 5050 projector over a 35-40ft long fiber Optic HDMI. The problem I am having is that the sound is lagging the Video and I have adjusted the audio delay settings all the way to zero and the audio is still lagging behind the video. It is worst in games but also very noticeable while streaming from the usual streaming apps. I also have DirecTV receiver feeding through the Marantz and it has the same issue, audio behind the video. The audio delay seeming is designed for when the Video lags the Audio but I am having the opposite problem. Any ideas on what could be causing this problem and how to fix?
