Microphone

[Ortferca]

I Have an xperia xa1, how to enable the principal microphone?

It depends on what app you are using, have you given it permission to access microphone

I'm trying to use it to answer phone calls.

Additionally, it usb port has been changed twice

Try to run system tests

Settings>support> Xperia Tests

Check if the microphone is working normally 

[Ortferca]

It runs ok

Additionally, I've got a sound meter app, it shows main microphone is not working, but the secondary functions properly 

[MarlonUk1]

check if the sound meter app has the right permission to access the microphone.

long tap the app> tap i>permissions

Yes, it has
