I'm not sure just when it started, but I noticed today (after latest update) that the video was not in sync on a number of YouTube videos I checked. I did some research and the good folks over at XDA said HTC told them to wipe the cache partition and this would solve the issue.
I did just that and now the lip sync issue is gone if anyone else has this problem as a number of posters at XDA had the same issue.
