microphone not working in other apps
Hello I am having issues with the microphone on an iPad air 2. Siri works, dictation works, when recording a video the mic works, however, the mic does not work in any other app ex: youtube. I have all apps enabled to access the microphone through the privacy section in settings, I have tried restoring from back-up and restoring as a new device but the problem remains. any help would be greatly appreciated. thank you.
iPad Air, iOS 8.4
