Check the selected microphone, app permissions, input level and headset connection when a PC microphone is not detected.
Try these checks in order
Save work if possible. Complete one check at a time and retest the original symptom. Stop when the issue is resolved.
01Select the correct input
Open Settings > System > Sound, choose the intended microphone and watch the meter while speaking.
02Check permissions and mute
Review Windows and app microphone permissions, headset mute switch and Bluetooth connection.
03Compare a trusted app
Test a trusted second app. Use official Windows or computer-maker updates if device detection is the problem.
How to read the result
A working Windows input meter with a silent meeting usually indicates app selection or permissions; no input across apps calls for broader device checks.
Use the input meter to locate the break
If the Windows input meter moves while you speak but a meeting app receives no sound, check that app's selected microphone, mute state and permission. If the meter never moves in any app, check the physical mute, selected input, privacy controls and device detection. Test only with an app you trust.
Before changing more settings: Record the selected input device, whether its Windows meter moves, which apps fail, and the permission or mute state.
Do not grant microphone access to unknown apps or bypass organization controls.
