Microphone not working in a meeting: check the selected input

Check the meeting app, selected microphone and device permissions before buying a replacement headset.

Start with the exact symptom: no input, very quiet sound or the wrong microphone being used. Check physical mute switches and the app's mute state. A headset can be connected for playback while another device remains selected for recording.

Test outside the meeting

Use a built-in recording tool or the platform's test call if available. Record a short phrase and listen back. If it works outside the meeting app, focus on that app's selected input and permissions.

Check operating-system microphone access using official instructions. On a managed device, organisation settings may apply; ask support rather than trying to bypass them. Close applications that may be using the device and retest normally.

Check the connection

Reconnect the headset to a supported port and inspect obvious cable damage. If using Bluetooth or an adapter, check the device and platform's supported call mode. A passive adapter cannot necessarily convert every headset connection.

Test a known-good compatible microphone if available. Change one part at a time so the result identifies something useful.

Before replacing hardware

Check physical and app mute states.
Record a sample outside the meeting.
Confirm the selected input and microphone permissions.

USB headset

Consider one when the existing hardware is faulty or cannot support the required connection. Check computer and platform compatibility, then test a recording before relying on it for a meeting.

Headset adapter

Match the exact headset plug and computer sockets. An adapter that physically fits may still route microphone and headphone signals incorrectly for your setup.
