Troubleshooting Mac Sound:

What to Try:

• Raise the Volume: If sound is not working, then raise the volume.

• Remove External Devices: Verify what your output item is. Also, disable Bluetooth, if enabled.

• Go Here: If the Internal Speakers on your Mac aren't Working - Apple Support

• Restart the Mac:

Perhaps you've unknowingly installed an update, and all needs to rest. For, restart the Mac. See if it then works.

• 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.

• 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

Try using Apple Diagnostics: Use Apple Diagnostics to test your Mac - Apple Support

I have this exact same issue on a Macbook 14 inch with an M1 pro chip
