Zoom can't detect camera or microphone
Check operating system permissions, restart Zoom app, or unplug and replug USB devices. Make sure you granted Zoom permission to use camera and microphone.
Zoom can't detect devices because OS permissions are missing, drivers are outdated, USB devices are disconnected, BIOS has device disabled, or the app cache is corrupted. Fix by granting permissions, restarting Zoom, reconnecting USB devices, checking BIOS, or updating drivers.

Skip — I just want a technicianCommon mistakes to avoid
- Not realizing OS permission is separate from driver — need both
- Not checking physical connection before software troubleshooting
