How to Manage Microphone Permissions in Chrome

Before you start

Microphone access in Chrome is controlled in three places: the site permission prompt, Chrome site settings, and the operating system privacy or microphone settings. For a website or web app to capture audio, access must generally be allowed at both the browser and operating-system levels. Chrome itself requires a secure context for microphone use, so the site is normally loaded over HTTPS or from a localhost address.

The process is local to your device. Chrome does not need a separate service, but some web calling tools may need their own account or service after the microphone permission has been granted.

Step-by-step instructions

Allow or block a site when prompted

• Open the page that wants to use the microphone.
• When Chrome shows the permission prompt, choose Allow to grant access or Block to deny it.
• If you want the decision to apply to future visits, keep the site listed in site settings; Chrome remembers the choice until it is changed.

Change microphone permission from Chrome settings

• Open the Chrome menu and select Settings.
• Go to Privacy and security, then Site settings.
• Open Microphone.
• Check the default behavior near the top. If Sites can ask to use your microphone is selected, Chrome will prompt before a site accesses the input device. If Don't allow sites to use your microphone is selected, sites are blocked by default.
• In the Allowed to use your microphone and Not allowed to use your microphone sections, find the site you want to change.
• Select the site entry and change its permission to Allow or Block. You can also remove the site entry so Chrome asks again on the next visit.

Select the input device

When the site calls getUserMedia or starts an audio or video call, Chrome uses the default input device unless the site offers its own device picker. You can change the active microphone from the call tool when that option is available, or from the operating system sound settings. Chrome may show the current site as using your microphone in the address bar while capture is active.

Check operating-system permissions

If Chrome is blocked at the system level, the browser cannot pass microphone access to a site. On Windows, check Privacy and security microphone settings and make sure microphone access is enabled for desktop apps. On macOS, check the microphone list under Privacy and Security and confirm that Chrome is enabled. On Android, confirm the Chrome app has Microphone permission in the device app settings. On ChromeOS, use the audio input setting and allow the requested site after Chrome prompts.

Check the output

To verify that a site can capture audio, use the site's own microphone test or recording control. A visible input level indicator or recorded playback confirms that the browser received audio. If you do not hear anything, do not assume the recording is silent; confirm that the correct output device is selected and that the site is not muted in the tab or in the operating system volume mixer.

The delivered audio format depends on the site implementation and the browser. Some sites capture speech-quality mono audio, while others request a higher sample rate or stereo. Chrome may apply processing such as echo cancellation or noise suppression depending on the capture constraints chosen by the site, so the result may not be a raw unprocessed recording. Background noise and input level behavior should be checked in the site's preview or recording rather than inferred from the permission settings.

Common problems and next steps

Chrome does not show a microphone prompt

If the prompt does not appear, the site may already have a saved answer, the default may be set to block, or the operating system may be preventing access. Open Chrome site settings for the site, check whether it appears under blocked entries, and change it to Allow if you intend to grant access. Then reload the page. If the site still cannot access the microphone, check the browser and system permission states again.

The wrong microphone is being used

Chrome normally uses the default input device chosen by the operating system. Set the intended microphone as the default input device in the system sound settings, then reload the page or restart the call. If the web app has its own device selector, choose the correct microphone there first.

Audio is too quiet or noisy

First check the input level in the operating system sound settings and the site's own preview. Move the microphone closer, reduce obvious background noise, and make sure the input level is not muted or set near zero. If the site offers noise suppression or echo cancellation, test with those settings enabled and disabled to see which gives a clearer result for the current environment.

Permission is allowed but a call still fails

Confirm that the page is open in the tab you intend to use and that the tab is not muted. Check whether another application is using the microphone exclusively, and close it if necessary. If the web app has its own privacy or device settings, review them as well. As a reversible check, remove the site from Chrome's microphone site settings, reload the page, and allow the prompt again.
