Webex Mic Test & “Microphone Not Working” Fix

Step 1: Does your mic work at all?

Click Test my microphone above and speak:

• The bar moves here — your mic and drivers are fine; the problem is in your Webex settings. Go to Webex audio settings.
• The bar does not move here — the issue is system-level (permission, device or driver), not Webex. See System-level fixes.

Step 2: Fix Webex audio settings

Open Audio settings (▾ next to Mute) → Speaker and Microphone, then:

1. Open Audio settings. Click the ▾ next to Mute → Speaker and Microphone (or Settings → Audio).
2. Pick the right Microphone. Set Microphone to the device that worked above and use Test.
3. Connect audio. Make sure you chose Call using computer when joining, not Don't connect audio.
4. Unmute. Confirm the Mute button is off and the host has not muted attendees.

Webex-specific gotchas worth checking

Webex asks how you want to connect audio when you join — if you picked Don't connect to audio or Call me, your computer mic is intentionally unused. Open the Audio menu and switch to Use computer for audio. Webex also defaults its noise removal to a high setting that can clip soft voices; drop it to Low or off under Audio settings.

The desktop Webex app and the web app keep independent device selections, so a mic set in one will not carry to the other. Webex's Test button in the Speaker and Microphone panel plays a level meter — if it moves there but the room cannot hear you, you are muted (look for the host's mute on entry).

Step 3: System-level fixes (if the test above also failed)

If the volume bar did not move in the test, the problem is your device or OS, not Webex. Fix it here, then retest.

Windows 10 / 11

1. Settings → Privacy & security → Microphone: enable Microphone access and allow desktop apps (and your browser).
2. Settings → System → Sound → Input: select the correct device and confirm the meter moves.
3. Right-click the speaker icon → Sound settings → Recording: set your mic as the Default device and enable it.
4. Close other apps holding the mic (Zoom, Teams, Discord, OBS) and restart Webex.

macOS

1. System Settings → Privacy & Security → Microphone: enable Webex (or your browser), then quit (Cmd+Q) and reopen — macOS only applies the permission after a restart.
2. System Settings → Sound → Input: choose the right device and check the level.

Webex in the browser (web client)

If you joined Webex from a browser, click the mic icon in the address bar, choose Allow, and reload. The web client uses the same browser microphone permission as the test on this page.

Webex on phone (iOS / Android)

Open your phone Settings and enable the Microphone permission for Webex, then reopen the app and rejoin. In the call, tap the screen and confirm you are not muted.

Step 4: Last resorts

• Update Webex to the latest version (older builds have audio device bugs).
• Update or reinstall your audio/headset driver and reboot.
• Sign out and back in, or do a clean reinstall of Webex.
• On a USB headset, try a different port and confirm it is selected as both the microphone and speaker.
