Whenever I receive a FaceTime call it does not ring I have checked in settings to make sure the noises and alert ect. Are all turned on.u
There have been many, many users reporting problems with FaceTime since April 16th. This was Apple's response to the problems.
It doesn't deal with sound issues however. Can you still make and receive FaceTime calls with no other issues? Are you getting all other notification sounds?
This used to show up as a question with some frequency - but i havent seen it in the last year. used to be a pad 2 issue, and I see you have a pad 2. While i had the pad 2, that would be a problem from time to time - but went away, and I was never clear on the cause.
So - the basics. You have already checked in notifications, and the alert spound is on. Ringer and alerts volume slider is not all the way down? (this is the only app that uses the ringer - as far as I know)
System sounds are on? (pad is not muted)
I would suggest you continue to play around with the settings. (You can facetime yourself from your iphone -if you are so equipped - so quick tests are easy)
