Hello Sanan13pro,
Apple Support Communities is a great place for help with the microphone on your Mac.
To confirm, the microphone appears to work with Siri, but not other apps and features. You’ve also verified that the Internal Microphone appears and is selected in System Preferences > Sound on the mac.
Those are great steps, and we’re glad you had the chance to verify that the Internal Microphone is selected. To confirm, have you verified the application in question has the correct audio input selected and not muted? If not, this can be a helpful step. If the issue is happening with multiple applications, try booting the Mac in to safe mode to see if the issue persists. You can find the steps for booting in to safe mode in the article below.
