Troubleshoot the Mac Audio:

What to Try:

• Unmute the App:

If an app has its own audio input and output settings, then perform things on the app itself.

• Remove External Devices:

Verify what your output item is.

• Disable Bluetooth:

If there are any microphones nearby, then they may be getting in the way via bluetooth.

• Go Here: Control Access to your Microphone on Mac.

See if an app is permitted to use your microphone.

• Reset the SMC and your NVRAM:

Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Sound) become manipulated, technically. So, reset the SMC and NVRAM.  (Applies to Anted-Based Macs Only)

• Boot into Safe Mode:

When you boot into Safe Mode, items load by default, with certain settings and caches set aside. So, hold down the shift key upon boot. See what happens then.

• Create a New Administrator:

See if creating and logging in as a new administrator does the trick. There may be something misconfigured in your current user - something that is getting in the way. Go to: System Preferences > Users & Groups > Unlock > Click: "+" > Create the new administrator

Do you have it set to internal speakers in the sound preference pane?
