"Zoom meeting - no sound: Been there, done that. My computer is saying I have no input or output sound devices. I will contact Apple support tomorrow."

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