The Blu-rays I am having audio issues with are:
The Godfather Part II (German individual Blu-ray Disc, not part of a collection set)
The Green Mile (German Blu-ray Disc)
Schindler´s List (German 4k remastered Blu-ray Disc)
Gandhi (French Blu-ray Disc)
All editions were bought brand new about half or a year ago. There are no scratches, fingerprints or similar stuff on the discs. My Sony Blu-ray player (SONY BDP-S1700, region b) is constantly in use (at least one movie or episode a day) and I have had no problems over the past two years, since I have bought my player or other technical equipment (headphones, HDMI-cable, etc.) in brand new condition. The issue only occurred with the above mentioned movies that are almost or over three hours long. Other movies, that are shorter or only quite a bit shorter like the German standard Blu-ray release for "Saving Private Ryan" played fine. I also watched the German edition of "Avatar: The Way Of Water" on Blu-ray and had no issues of any kind.
The four discs play fine until I would reach the last 10-15 minute or so. Then, suddenly, the audio is missing. No skipping , just entirely gone for the rest of the movie. If I pause the movie, rewind it a a few seconds or minutes and start playing again, it works fine.
Someone suggested it might be a player glitch. But the latest firmware update did not work. Do you have any other suggestions?
