Hi PaulIverson and thanks for reaching out. My name is Joseph. I'm an independent advisor. I'll be happy to help you out today.
I would suggest you refer to the below steps and check if it helps to resolve the issue.
- Please press the Windows key and type in Settings and press enter.
- Navigate to System > Sound.
- On the Right side click on Microphone privacy settings.
- Scroll down and under the "Choose which Microsoft Store apps can access your microphone" toggle off the 'ZOOM' app.
- Restart your computer, and when it boots up, check to see whether or not the problem has been resolved.
I hope this helps. Feel free to ask back any questions and let me know how it goes.
Thank you!
