Troubleshooting
Microphone Not Working in Your Browser? Step-by-Step Fixes
A microphone not working in the browser is usually a permission or a wrong input device. Check the address bar for a crossed-out microphone and allow it, make sure the browser is using the mic you're speaking into, then check your system's privacy settings and any mute switch on your headset or keyboard.
Before you change anything, rule out the simplest cause: on a video chat you might be muted on the site itself, or the other person might have muted you.
Is it really your mic? Rule these out first
- You're muted on the site. On Omlet, the microphone button on your own video shows a crossed-out mic when you're muted. Tap it to unmute.
- Your partner muted you. Omlet lets people mute their partner, so one person not hearing you doesn't prove your mic is broken. Press Next and see whether the next person can.
- The mic button can't be pressed. On Omlet that means the browser gave the site your camera but no microphone. Work through the fixes below.
- A hardware mute is on. Headset cables, USB mics and many laptops (a function key with a crossed-out mic) have their own mute, often with a small red light.
- It's a Bluetooth headset. Those have their own quirks; see Bluetooth headset mic not working.
Fix 1: Give the website microphone access
Most video chat sites ask for camera and microphone together, but it's easy to allow one and block the other. Here's where each browser keeps the setting:
| Browser | Where to allow the mic |
|---|---|
| Chrome | Icon left of the address → Microphone on, or chrome://settings/content/microphone |
| Edge | Padlock or site-information icon → Permissions for this site, or edge://settings/content/microphone |
| Firefox | Crossed-out mic icon in the address bar → clear the block, or Settings → Privacy & Security → Permissions → Microphone |
| Safari on Mac | Safari → Settings → Websites → Microphone |
| Safari on iPhone | Page menu (aA) → Website Settings → Microphone, or Settings → Apps → Safari → Microphone |
| Chrome on Android | Icon left of the address → Permissions → Microphone |
Reload after any change. How to tell it worked: the browser shows a microphone or recording indicator on the tab or in the address bar while the site is listening.
Fix 2: Browser not detecting the right microphone
A site gets one microphone, and the browser often hands it the system default, which might be a webcam mic across the room, a headset that's switched off, or a virtual device.
- Chrome and Edge: the dropdown at the top of chrome://settings/content/microphone (or edge://settings/content/microphone) sets which mic sites get.
- Firefox: the permission prompt has its own microphone dropdown. Clear the site's permission and reload to choose again.
- Safari: uses the Mac's input device, set in System Settings → Sound → Input.
- Windows default: Settings → System → Sound → Input, then choose your device. Avoid Stereo Mix, which records what your speakers play rather than your voice.
Noise-removal and streaming apps often create a virtual microphone. If your browser is set to one of those, the app has to be running; otherwise the virtual mic sends silence.
Fix 3: Check system privacy settings for the microphone
- Windows 11: Settings → Privacy & security → Microphone → turn on Microphone access and Let desktop apps access your microphone. On Windows 10 it's Settings → Privacy → Microphone.
- macOS: System Settings → Privacy & Security → Microphone → switch on your browser, then quit it and reopen.
- iPhone: Chrome, Firefox and Edge each have a Microphone switch under Settings → Apps → the browser's name. Safari uses the website settings in fix 1.
- Android: App info for your browser → Permissions → Microphone. On Android 12 and later, also make sure the Microphone access tile in Quick Settings is on.
If the camera works but the mic doesn't, the camera and microphone switches are separate everywhere. Allowing one never allows the other.
Fix 4: Check input levels, boost and exclusive mode
If the mic is allowed and selected but people hear you faintly or not at all, look at the signal itself.
Windows
- Settings → System → Sound → select your input device. Speak and watch the level bar, and set Input volume well above zero.
- For more control, open More sound settings (Sound Control Panel on Windows 10) → Recording tab → your mic → Properties.
- On Levels, raise the volume and, if your mic offers it, Microphone Boost.
- On Advanced, try unticking Allow applications to take exclusive control of this device, so one app can't lock your browser out of the mic.
Mac
System Settings → Sound → Input: select your mic, speak, and watch the input level. Drag Input volume up if the bars barely move.
Test your mic one layer at a time
- System: record a few seconds with Sound Recorder or Voice Recorder (Windows), Voice Memos or QuickTime (Mac), or your phone's recorder app. If that's silent, the browser isn't the problem; check the hardware and fix 4.
- Browser: with the site open, check that the tab shows the mic indicator and that the site's permission panel lists the right device.
- Live call: talk to someone and ask. If one person can't hear you and the next one can, the first probably muted you or had their volume down.
Our webcam and microphone test routine adds a camera check before calls. Once people can hear you, sounding better on video calls helps with clarity.

| Symptom | Likely cause | Fix |
|---|---|---|
| Crossed-out mic in the address bar | Site blocked | Fix 1 |
