Hi DPV_18,
Thanks for contacting Apple Support Communities!
It appears that your Mac microphone isn't working as you'd expect.
If you go to the Apple Menu > Settings > Sound, are you able to increase the “Input volume” via the slider?
Also, does this happen in specific apps or all apps? If it's happening in more than one app, you can follow the steps outlined here to help isolate this behavior further: If you can’t record audio on a Mac using macOS Mojave or later
"In macOS Ventura
- Quit the app you're using to record audio.
- Choose Apple menu > System Settings, then click Privacy & Security.
- Click Microphone.
- Turn on the setting for each app that needs access to the built-in mic, an external USB mic, or the inputs on an external audio interface.
- Open the app and try to record audio again."
You can also set up a new user account to test your microphone.
To set up a new user account, you can go to the Apple menu > System Preferences, then click Users & Groups. Click the lock, then enter an administrator name and password.
Click the add button (+) below the list of users.
Complete the fields shown for an Administrator account, then click Create Account (or OK).
Once you've set up the new user account, you can go to the Apple Menu and choose Log Out then sign into the new user account to test the microphone.
If you still experience the same behavior in a new user account, you may also consider running a diagnostic test on your Mac to check its hardware: Use Apple Diagnostics to test your Mac
We hope this helps.
Cheers!
