To enable your microphone, allow access in your device’s privacy settings, choose the correct audio input, and check the permission for the app or website you want to use. If one layer blocks access, a microphone can work in a system test but remain silent in a call or recording.
Start with the settings for your device below. Then make a short test recording before joining a call or recording an important walkthrough. Menu labels can vary with your software version and device manufacturer.
Quick microphone settings guide
| Device or browser | Where to check access | Also check |
|---|---|---|
| Windows 11 | Settings → Privacy & security → Microphone | System → Sound → Input |
| Mac | System Settings → Privacy & Security → Microphone | Sound → Input |
| Chrome on a computer | Settings → Privacy and security → Site settings → Microphone | Site permission and selected microphone |
| iPhone | Settings → Privacy & Security → Microphone | Permission for the affected app |
| Android | Settings → Apps → the app → Permissions → Microphone | Device-wide microphone access |
Before changing settings: check mute and connections
- Check the microphone’s physical mute switch and the mute control inside your call or recording app.
- Reconnect a wired microphone or headset and check that it appears as an input device.
- For a wireless headset, check its charge and connection.
- Confirm which device the app is using; it may have selected a laptop microphone instead of your headset.
- Test with a short recording so you can hear the result, rather than relying only on an animated level meter.
Use our webcam and microphone test for a browser check. The browser will request permission when needed. Grant access only to the app or site you intend to use.
How to enable a microphone on Windows 11
- Open Start → Settings → Privacy & security → Microphone.
- Turn on Microphone access and Let apps access your microphone.
- Enable the relevant app where individual controls are available. For desktop applications, check Let desktop apps access your microphone.
- Return to your app and test again.
See Microsoft’s microphone-permission instructions for the current controls. If you still use Windows 10, its access controls are under Settings → Privacy → Microphone; the Windows 11 path is different.
Select and test the Windows input device
Open Settings → System → Sound. Under Input, select your microphone and open its properties. Use Start test, speak normally, stop the test, and play the sample. Adjust the input volume if needed. Microsoft’s microphone setup and testing guide explains this check.
If the device works here but not in your application, check that application’s input selection and permissions next. A missing device and a denied permission are different problems.
How to enable a microphone on Mac
- Open the Apple menu → System Settings → Privacy & Security.
- Select Microphone.
- Turn on access for the app you intend to use. For a website, check the browser’s access as well as the site’s permission.
These steps follow Apple’s Mac microphone-access guide. Older macOS versions may call the settings app System Preferences.
To select the audio source, open System Settings → Sound → Input and choose the intended microphone. Speak and check the input level. See Apple’s sound-input instructions. Follow any prompt to quit and reopen an application after changing permission.
How to allow microphone access in Chrome
- Open Chrome Settings → Privacy and security → Site settings → Microphone.
- Select the microphone you want to use.
- Review the allowed and blocked sites. If your intended site is blocked, open its entry and change its microphone permission to Allow.
- Return to the site and retry the call or recording. Respond to the permission prompt if it appears.
Chrome also needs microphone permission from your operating system. Follow any prompt to open system settings or restart the browser. On a work or school computer, an administrator may control these permissions. Google’s Chrome microphone guide documents both site and system access.
For other browsers, use their own site-permission controls. Avoid changing every site’s access when only one website is affected.
How to enable a microphone on iPhone
For an app that cannot use the microphone, open Settings → Privacy & Security → Microphone and enable the affected app. If the app already has access or is absent from the list, Apple recommends contacting its developer.
To check whether your voice is being captured, record and play a short Voice Memo. Apple’s iPhone microphone troubleshooting guide also explains checks for call and camera-recording problems. If recordings remain unclear across apps, the issue may need device service rather than another permission change.
How to enable a microphone on Android
- Open Settings → Apps and select the affected app.
- Open Permissions → Microphone.
- Choose an available access option, such as allowing use while the app is open.
- Check device-wide access under Security & privacy → Privacy → Privacy controls if microphone access is turned off for the whole device.
Android labels vary by manufacturer and version. Google’s app-permission guide explains the available choices. A browser-based call may require both browser app access and website permission.
Microphone still not working? Follow the symptom
| Symptom | Next check |
|---|---|
| Microphone is missing from the input list | Connection, pairing, compatibility, and the device manufacturer’s guidance. |
| System test works, but one app is silent | That app’s permission, mute control, and selected input. |
| Browser says access is denied | The browser’s operating-system permission and the site’s permission. |
| Sound is faint or distorted | Input level, microphone position, and a playback test. |
| Settings are unavailable or greyed out | Whether the device or browser is managed by your organization. |
Save your work before restarting the affected application or device. Change one thing at a time and repeat the same short test so you can tell what helped. If you need further support, record the device model, operating-system version, app or browser, selected input, exact error, and tests already tried.
For a support conversation, a screen recording can show the settings and error even when narration is unavailable. Add a written explanation, and keep unrelated account details out of view. Our report templates can organize the handoff.
Frequently asked questions
Why does my microphone work in one app but not another?
Access, input selection, and mute controls can differ by app. Compare the affected app with the working one, then repeat a short recording test.
Does microphone permission also record computer audio?
No. Microphone access and capturing a computer’s playback are separate capabilities. Test the sources your recording needs; see our internal-audio recording guide for that workflow.
Should I reinstall audio drivers first?
Start with connections, mute, input selection, and permissions. If the device is not detected, use the manufacturer’s support instructions before changing drivers or software.
What if I cannot change microphone access?
Ask the administrator of a managed device or browser to check the policy. Provide the affected app or website and the error you see.
