Just today on my I pad 4 gen. I go to a video, and the audio starts, but the video does not show up until I hit the the pause and play button. Then the video races forward to catch up with the audio, then freezes there, I then push pause and play and the same thing happens. On the rare occasions when I can get the video to play, it is always out of sync. I thought maybe it was not a fault of the iPad, and just that of the site. But when I went to a complete different site the same thing happened. Another test I did was go to a site with my iPad, and with my iPad mini, to the very same site, the mini played the video and audio perfectly in sync. The newer iPad was doing the same thing. Is there a setting in settings that I have disabled or something?
