iPad Pro 12.9 4th Gen Microphone Issue

I am facing a problem with my iPad microphone. The microphone works fine with the Camera App and the voice memos but not with any other application (FaceTime, Instagram, Games, and so on). I have tried multiple troubleshooting steps, and nothing seems to work. I took the iPad to an Authorised Service Center, and they found no hardware issues.

I tried doing a Factory Reset for the iPad using recovery mode on iTunes, but It did not work. I have tried checking the Privacy Setting, and everything seems fine.

I started facing this problem in IOS 17.1 forward. The service center has no further solutions as they could not identify issues with the iPad.

I have contacted Apple Support multiple times, and nothing seems to work.
