Zoom Microphone Not Working

Last reviewed · fixmic team

Zoom shows you as connected but no one can hear you. This page covers the five settings that account for nearly every Zoom mic failure in the current Zoom Workplace client. Start with the quick fix.

Try this first

In your Zoom meeting, click the up-arrow (^) next to the Mute button → 'Audio Settings…' → 'Test Mic'. Speak. If the input level bar moves, you're unmuted but the wrong device was selected — pick the right microphone from the dropdown above the test button.

1. Confirm you are not muted

Zoom has three layers of muting — and any one of them silences you.

  1. Meeting mute

    If the microphone icon has a red line through it, you're muted. Click it, or press Alt + A (Windows) / Cmd + Shift + A (macOS). Push-to-talk: when muted, hold Spacebar to speak temporarily.

  2. Host muted you

    Hosts can mute participants. You'll see a small notification near the top of the window. Click 'Unmute' to request unmuting — the host has to allow it.

  3. Hardware mute

    Many headsets and USB mics have a physical mute button or LED. Check the in-line remote on your cable and any button on the microphone body itself.

2. Grant Zoom microphone permission

On a fresh install or after a major OS update — especially Zoom 6.0+ or Windows 11 24H2 — Zoom may have lost mic permission.

  1. Windows: Settings → Privacy & security → Microphone

    Confirm 'Microphone access', 'Let apps access your microphone', and 'Let desktop apps access your microphone' are all on. 'Zoom Workplace' (or 'Zoom') should be listed under desktop apps.

  2. macOS: System Settings → Privacy & Security → Microphone

    Toggle Zoom on. macOS requires you to fully quit (Cmd + Q) and reopen Zoom for the change to apply. The bundle ID stays 'us.zoom.xos' despite the Workplace rebrand.

  3. Browser-based Zoom (app.zoom.us/wc/join)

    Click the site-information icon (formerly the lock, now a tune/slider icon in Chrome and Edge) on the left of the address bar → set Microphone to Allow → reload the page.

3. Pick the right input in Zoom's audio settings

Zoom has its own device picker that overrides whatever you chose in Windows or macOS sound settings.

  1. Open Audio Settings

    Click your profile picture (top-right) → Settings → Audio. Or in a meeting: up-arrow next to Mute → Audio Settings…

  2. Match the Microphone dropdown to your actual device

    If 'Same as System' is selected and the OS default is wrong, Zoom uses the wrong device. Pick your microphone by name.

  3. Speak and watch the Input Level bar

    If it moves, settings are correct. If not, the microphone or its OS permissions are the problem — not Zoom.

4. Tune Zoom's audio processing

Zoom Workplace processes input heavily for noise and echo. On some setups this processing makes you inaudible even when the raw signal is fine.

  1. Audio Settings → Suppress background noise

    Options are Auto / Low / Medium / High. Aggressive suppression (High) can mistake a quiet voice for noise. Drop to Low if you're being clipped.

  2. Audio Settings → Audio profile

    Default is 'Zoom default (Noise removal)'. If you're doing music or want unprocessed audio, switch to 'Live performance audio' (formerly 'Original sound for musicians').

  3. Audio Settings → Advanced

    Set 'Echo cancellation' to Auto. On Windows you'll also see 'Signal processing by Windows audio device drivers' and 'Windows system audio enhancements' — set both to Auto unless OEM drivers are causing issues, then try Off.

  4. Disable auto-adjust if your level fluctuates oddly

    Audio Settings → uncheck 'Automatically adjust microphone volume' if your voice goes loud-soft-loud during calls.

5. Quit conflicting apps and rejoin

If another app grabbed the microphone before Zoom did, Zoom may show a device but get no audio from it.

  1. Quit Discord, Teams, Meet, OBS, and Audacity

    Close every app that uses the mic — fully quit, not just minimize. Then leave the Zoom meeting and rejoin.

  2. Restart Zoom

    Right-click the Zoom icon in the system tray (Windows) or menu bar (macOS) → Quit. Reopen. The new session will reacquire the microphone cleanly.

Still no audio in Zoom?

Verify the microphone works outside Zoom first:

  • Run the live test on the fixmic homepage. If the meter moves, the mic works — the problem is inside Zoom.
  • If the live test shows nothing either, the issue is OS-level. See the Windows or macOS guide.
  • Try the browser web client (app.zoom.us/wc/join) as a sanity check — it uses the browser's audio stack, not the desktop client's.
  • On Windows 11 24H2 a documented regression broke mic access for Zoom and Teams on some systems; recheck OS permissions after major updates.
