How to Select and Configure a Microphone in Google Chrome

Before you start

A working microphone should already be connected to the computer and recognized by the operating system. Chrome does not install its own microphone driver, so if the microphone is missing from the operating system sound settings, it will not appear in the browser either. The process described here runs locally in the browser. No Google account or Chrome sync service is required to choose or test a microphone.

Step-by-step instructions

Chrome offers two main places to manage microphone behavior: the site permission prompt and the browser-level privacy settings. Site permissions control which sites may use the microphone. Browser settings control the default input device and, through the operating system, qualities such as the input level.

Change the default microphone

Open Chrome, select the three-dot menu in the top-right corner, then choose Settings. Select Privacy and security, then Site settings. Under Permissions, open Microphone. Here you can see the default behavior for sites and the list of sites that are allowed or blocked from using the microphone.

To change the microphone that Chrome uses by default, return to the site settings page where a microphone permission is requested. Click the camera icon or microphone icon in the address bar while the site is open. In the permission panel, open the microphone dropdown and choose the preferred input device. The selected device applies to that site and normally remains in effect for subsequent visits.

Version differences can affect the exact wording. Newer Chrome versions group microphone and camera permissions under Site settings, while some older builds may place the input device selector directly in the permission bubble. The underlying order is the same: open the site, use the address bar icon, then select the input device.

Set the input level and operating-system permissions

Chrome passes the selected device through to the operating system, so the input level is usually adjusted in the operating system sound settings. On Windows, open Sound settings and use the Input section for the selected microphone. On macOS, open System Settings, select Sound, then choose Input. On ChromeOS, open the audio settings from the status area and select the input device.

The operating system must also allow Chrome to access the microphone. Check the operating-system permissions for the browser or for the app that hosts the call. In Windows privacy settings, microphone access can be enabled or disabled for desktop apps. On macOS, Chrome appears under Microphone in Privacy and Security settings. On ChromeOS, the site permission in Chrome is normally the main gate.

A sample rate is normally negotiated automatically between Chrome, the operating system, and the site. You usually do not need to change it manually unless a specific recording or conferencing tool exposes its own audio format settings.

Check the output

The quickest way to confirm that the microphone is working is to use the site that needs it. Open the site, start a test call or recording, and confirm that the input indicator moves when you speak. If the site offers a preview meter, use it to check that the input level is neither too low nor clipping.

Keep in mind that the quality you hear depends on the site's audio processing, the microphone, and the current background noise. A browser test confirms that the microphone is being used; it does not guarantee the final recording or call quality.

Common problems and next steps

If the site does not ask for microphone permission, open the address bar icon and choose Allow. If Microphone is already set to Allow but the site still gets no audio, close other apps that may be using the microphone, then reload the page.

When the microphone is not listed in Chrome, check the operating system sound settings first. Confirm that the device is enabled, selected as the input device, and not disabled by an operating-system permission. On Windows, also check the privacy microphone setting for desktop apps. On macOS, confirm that Chrome is allowed in the microphone privacy list.

If the microphone is listed but sounds quiet or noisy, raise the input level in the operating system and reduce obvious sources of background noise. For calls, prefer a headset or a microphone positioned close to your mouth. If the audio still sounds wrong, test the microphone in another browser or a simple recording app to determine whether the issue is in Chrome, the operating system, or the site.

If the site was blocked earlier, open Settings, go to Privacy and security, then Site settings, and select Microphone. Remove the site from the Blocked list or change its permission to Allow. Removing a site from the exceptions list resets it to the default behavior, so Chrome will ask again the next time the site requests the microphone.
