I don't know if this is the right forum, if not, move me. Post upgrade, while opening videos in Facebook posts. At first, the videos just didn't play, or they would only play for a short period. Now, there is no volume. This wasn't occurring in iOS 6. Anyone know what the problem could be?
I'm going to be of no help, cause I can't replicate your issue. On my timeline, all videos play with sound. This includes videos on a page I manage.
Just wanted to acknowledge your issue and wish you luck. Sorry.
