Microphone always turned off on resume from background

Build Platfrom : Mac OS X 12.3.1, XCode 13.2.1

Target Platform : iOS 15 later

Hi, There ~

I have some problem. since upgrading iOS to version 15, there has been a problem with the app microphone. When the app goes to the background and returns to the foreground, the microphone that was working well does not work. It always worked well in iOS version 14, but I don’t know the reason. anyone know this issue?

somebody help me ~

I found something that my app is installed on iOS 15.6

my app is built with Xcode 13.2.1

I think it is related to the versions of between Xcode and iOS version.
