Zoom Audio Not Working? 7 Fixes for Every Device

This is an independent guide. Not affiliated with or endorsed by Zoom Communications, Inc.

You join a Zoom call, say hello, and get nothing back. No one can hear you. Or maybe you can't hear anyone else. You check your volume, unmute yourself, and still: silence.

Zoom audio not working is one of the most frustrating video call problems because it kills the entire point of the meeting. The good news: the cause is almost always a simple settings issue, a wrong device selection, or a permission that got flipped off.

This guide covers 7 fixes that work on Windows 10, Windows 11, Mac, Android, and iPhone. Start from the top and work down. Most people fix their Zoom audio within the first three steps.

Test Your Microphone and Speakers First

Before changing any Zoom audio settings, check whether your hardware actually works. Use our free online microphone test to verify your mic and speakers in the browser. It takes five seconds and tells you exactly whether the problem is Zoom or your device.

If the mic test shows your hardware is fine, the problem is inside Zoom. Keep reading.

What Causes Zoom Audio Problems?

Zoom audio failures fall into two categories: you can't hear others (speaker issue) or others can't hear you (microphone issue). Sometimes both break at once. Here are the 6 most common causes:

• Wrong audio device selected. If you have multiple audio devices (built-in speakers, headphones, Bluetooth earbuds, a USB headset), Zoom might pick the wrong one. This is the number one cause of Zoom audio not working on laptops.
• Muted without realizing it. It sounds obvious, but the host can mute you, or you might have joined with audio muted. The mute button in Zoom is small and easy to miss.
• "Join Audio" not clicked on mobile. On Android and iPhone, Zoom asks you to choose an audio connection method when you join. If you skip this step or dismiss the popup, you get no audio at all.
• OS-level microphone permissions. Windows 11, Windows 10, and macOS have system-wide privacy settings that block microphone access for specific apps. If Zoom isn't allowed, your mic stays silent.
• Another app is using the microphone. Your microphone can only serve one app at a time. If Teams, Discord, OBS, or a browser tab is using your mic, Zoom can't access it.
• Outdated Zoom client or audio drivers. Old versions of Zoom sometimes lose compatibility with newer audio hardware or OS updates. The same goes for audio drivers on Windows.

Your coworker Alex joins the Monday standup and types "can anyone hear me?" in chat for the third week in a row. The fix took 20 seconds once he checked his Zoom audio settings. That's the typical experience with audio issues. The cause is simple; finding it is the hard part.

Zoom Audio Not Working on Specific Devices

Some audio problems are unique to specific platforms. Here are targeted fixes for the most common ones.

Windows 11 and Windows 10

Windows has a separate "App volume and device preferences" panel (Settings > System > Sound > Volume mixer) that lets you set a different audio output per app. If Zoom is routed to the wrong device here, your global speaker settings won't help. Open the Volume mixer and make sure Zoom's output points to your actual speakers.

Also check Windows Audio Service: press Win + R, type services.msc, find "Windows Audio," and make sure it's running. If it's stopped, right-click and select "Start."

Mac

After macOS updates, microphone permissions sometimes reset. Go to System Settings > Privacy & Security > Microphone and re-check Zoom. If Zoom doesn't appear in the list, uninstall and reinstall it.

If you use AirPods or other Bluetooth headphones, macOS occasionally routes Zoom audio to the built-in speakers while keeping AirPods as the system output. Check the Zoom audio device dropdown (arrow next to Mute) to confirm.

Android and iPhone

The most common mobile audio problem is forgetting to tap "Call using Internet Audio" when joining. If you dismissed this prompt, tap the screen to show controls, then tap the audio icon (bottom-left) and select "Call via Device Audio."

Also check that your phone isn't connected to a Bluetooth speaker or car audio system that's out of range. Disconnect Bluetooth temporarily to test with the phone's built-in speaker.

Others Can't Hear You on Zoom: Microphone Fixes

If your speakers work fine but nobody can hear you talk, the issue is your microphone specifically. Here's a quick checklist:

1. Check the mic indicator in Zoom. When you speak, the microphone icon should show a green bar moving. If it stays flat, Zoom isn't receiving audio from your mic.
2. Run a mic test. Use our free online microphone test to check if your mic works outside of Zoom. If it works there but not in Zoom, the problem is Zoom-specific.
3. Switch microphones. If you have a USB headset and a built-in mic, try switching between them in Zoom's audio settings.
4. Check for a hardware mute switch. Some headsets and laptops have a physical mute button on the device itself. Look for a slider on your headset cable or a function key (usually F4 or F8) on your laptop keyboard.

Jenna, a project manager on a remote team, spent 10 minutes troubleshooting her Zoom microphone before noticing her USB headset had a tiny mute slider on the cable. She'd bumped it while adjusting her headphones. Ten seconds to fix; ten minutes of silence in the meeting.

Zoom Audio Not Working After an Update

Zoom updates sometimes change audio handling or reset preferences. If your audio stopped working right after updating, try these steps:

1. Open Zoom Settings > Audio and toggle "Automatically adjust microphone volume" off, then on again.
2. Change the speaker and microphone to a specific device instead of "Same as System."
3. Disable "Use Stereo Audio" under Audio > Advanced if it was enabled before the update.
4. If you're on Windows, check that the update didn't change your default audio device in Windows Sound settings.

Zoom occasionally introduces bugs in new releases that get patched within a week or two. If you suspect a bug, check the Zoom release notes for known issues. You can also roll back to a previous version by downloading an older installer from the Zoom download archive.

Want to skip the update cycle entirely? Tools like Flat.social run in the browser, so there's nothing to install or update. Your audio just works through your browser's standard permissions.

Zoom Audio Settings: A Quick Reference

Knowing where every audio toggle lives saves you time during future calls. Here's a map of the most important Zoom audio settings:

• Speaker and Microphone selection (Settings > Audio): pick specific devices instead of "Same as System" for reliable results.
• Automatically adjust microphone volume: leave this ON unless you use a professional mic with its own gain control.
• Suppress background noise: set to "Auto" for most environments. Switch to "Low" if Zoom is cutting off your voice in a quiet room.
• "Join audio by computer when joining a meeting" (checkbox): enable this so you never forget to connect audio.
• "Mute my microphone when joining a meeting": enable this if you often join calls from noisy locations.
• Audio profile (Settings > Audio > Advanced): "Music Mode" increases audio fidelity for music or presentations but uses more bandwidth.

Getting these settings right once prevents most recurring audio problems. If you set up a Zoom meeting for someone else, share these settings with them beforehand.
