Hello, thank you for reaching out to Microsoft Q&A.
If you think a driver update may be the cause, you can use System Restore to roll back to an earlier state.
- Click Windows + R key, type rstrui.exe, and click ok.
- Click Next.
- Select the date/time you would like to restore your computer.
- Click Finish.
If system restore does not resolve the issue,
- May I please know the make and model of your device? (Type msinfo in the search bar on the taskbar and click Enter. Post a screenshot of the resulting dialog box.)
- Do the Camera and microphone work outside the Zoom app, for example, in the Windows camera app or the sound recorder?
- May I please know the default audio input device selected in the system sound settings?
