FaceTime sound breaking up
i have an iPad Air, and for the first year I had it I was able talk over FaceTime with no issues. Recently, I've started having some issues when the other side is talking. If there is any noise on my end, the speaker cuts out like its muted. This wasn't something that was happening before, and it's getting really bad when 3 2 year olds are running around while talking to grandma and grandpa. I've tried a full reset and set up as new for my iPad, my parents are using new iPad Air 2's, and my internet connection is fairly stable.
What can I do to troubleshoot further? A full reset from iTunes?
iPad Air, iOS 8.1.3
