Taking up for example the answer of [Microphone not working on third party apps only (iPhone 6)](https://apple.stackexchange.com/a/285475/381223):

> Under `Settings` > `Privacy` > `Microphone` you'll be able to allow/deny each app that require the microphone to use it.

I do not see any apps in the list. I only see one item called "App Clips", and in that item, nothing is listed. How can I get back all of the apps that need the microphone?

The microphone is missing everywhere:
- filming with front or back camera,
- voice memos: you cannot even start the record,
- speech-to-text in Whatsapp, Telegram, Signal, Threema and just everywhere else,
- Siri,
- phone calls with or without headset.

The Apple headset itself does not work either: plugging it in and out does not lead to any change in the played media, it will just use the loudspeaker at any time.

This is just a list of examples that I tried, it is clear that it does not work anywhere else.

I have an iPhone 7 with iOS 15.6.
