How to Allow or Unblock Microphone Access in Chrome

Before you start

Microphone access in Chrome is controlled by two layers: the operating system and the browser. For a website or web app to use your microphone, the mic must first be available to the operating system as an input device. Chrome then decides which sites may request it and which input is selected for the current call or recording. These settings are stored locally on your device. Check that a working microphone is connected or built in, and close other apps that may be using the same input device if you need to isolate a permission problem.

Step-by-step instructions

The quickest path is to open the site or web app that needs the microphone and start its audio feature. Look for a microphone icon on the right side of the address bar. If allowed, the icon appears normally. If blocked, Chrome shows a crossed-out camera or microphone icon. Select that icon to open the site permission controls.

Allow access from the address bar

• Open the Chrome page where you want to use the microphone.
• Select the microphone or crossed-out mic icon in the address bar.
• Choose the microphone option and set it to Allow.
• Reload the page if Chrome asks you to refresh before the change applies.
• If the menu also shows an input selector, choose the microphone you want Chrome to use.

Change microphone permission in site settings

• With the site open, select the icon next to the address bar, then choose Site settings.
• Find Microphone and change the setting to Allow.
• Reload the page and test the audio feature again.
• To remove a saved setting, select the remove or reset option for that permission and reopen the site so Chrome asks again.

Change the default microphone permission in Chrome settings

• Open the Chrome menu and go to Settings.
• Open Privacy and security, then Site settings.
• Select Microphone.
• Choose your preferred default behavior, such as allowing sites to ask before using it.
• Review the Allowed and Not allowed lists and update individual sites if needed.

Chrome also has a setting that can require a site to ask again after the page is closed. If you want a permission to persist across visits without repeated prompts, review the permission duration or related site settings where available in your version.

Check the output

After allowing the microphone, return to the site and start its audio feature. You should see a visible indication that the mic is active, such as a level meter, recording timer, or the red recording dot in the Chrome tab. Speak at a normal volume and watch whether the input level responds. If the site offers a preview, use it to hear how the selected input device sounds before joining a call or recording.

The available quality depends on the microphone and the site. Chrome passes audio to the site, but the site can apply its own processing, such as noise suppression or echo cancellation. Background noise, sample rate, and local processing behavior should be checked in the app you are using rather than assumed from the browser setting alone.

Common problems and next steps

Chrome says the microphone is blocked to protect your privacy

This message appears when the site is not allowed to use the microphone, or when Chrome cannot obtain the necessary permission from the operating system. First open the address bar controls and set Microphone to Allow, then reload the page. If Chrome still reports that access is blocked, open the operating system privacy settings for the browser and confirm that microphone access is enabled there. On some systems, browser microphone permission must be granted separately from the site-level setting.

The microphone is allowed but no sound is picked up

• Open the Chrome address bar menu and confirm the correct input device is selected.
• Check the operating system sound settings and make sure the microphone is not muted and has a useful input level.
• Close other applications that may be holding the microphone.
• Disconnect and reconnect an external microphone, then reload the page.
• Use the browser-level or system-level preview to confirm the device is producing sound.

The site does not ask for permission

A saved Allow or Block setting can stop Chrome from showing the prompt. Open Site settings for that page, reset or remove the microphone permission, and reload the page. On a secure site, Chrome should then ask again when the page requests access. If the page never requests the microphone, check whether its audio control is enabled and whether the permission is controlled by a parent page or embedded frame.

Chrome is allowed but the operating system still blocks access

Open the system privacy or security settings for microphone access and locate the browser in the app list. Enable microphone access if it is off. After changing an operating-system permission, fully quit and reopen Chrome so the new permission scope is applied. If the browser is not listed, run the microphone feature once, then return to the system settings and check the list again.

Wrong input device is used

When several microphones are available, Chrome may select a built-in mic, headset, or interface channel that you did not intend. Open the address bar microphone setting or Chrome site settings and choose the intended input device. After changing devices, reload the page or restart the call so the app uses the new selection. If the expected device does not appear, verify that it is recognized by the operating system first.
