The complete Google Chrome audio muting guide

Websites and services that you open in Google Chrome may use the browser's audio playback capabilities to play audio. While audio playback is wanted most of the time, for instance when you click on the play button on YouTube to play a video or on Spotify's website to play a song, it is sometimes done without user interaction and often unwanted as a consequence in these situations.

Sites may display advertisement that uses audio, as video ads with sound, or play videos automatically when you visit them. There are other forms of audio content that you may find disruptive.

A short tab muting history and the status quo

First tab muting extension appeared in 2011 for the Chrome browser. The free extension MuteTab added basic audio muting options to Chrome. The extension lists sites that play audio and options to run mute and other audio related commands on the identified sites.

Google began to experiment with tab audio notifiers in Google Chrome in 2013; first, powered by the startup flag --enable-audible-notifications which Chrome had to be launched with, and then later on as a built-in feature that was enabled by default.

Chrome would displays a new icon on tabs that played audio to indicate to the user that audio was played on that site.

Tab audio indicators are part of any new version of Chrome. Google added an audio muting flag to Chrome in late 2014 which users could enable to mute the audio on sites by clicking on it. The, very comfortable, option is still experimental up to this day.

Google changed the tab muting functionality of the browser in 2017. The company removed options to mute individual tabs in the browser in favor of a site-wide mute.

As far as Chrome's current functionality is concerned:

• Google Chrome displays audio icons on tabs when a site plays audio.
• Google Chrome supports tab-based audio muting controls but they are disabled by default.
• Chrome supports Sound controls to allow or blocks sites from playing audio, or display a prompt whenever an attempt is discovered.

Good to know

• If you play a video without audio, no audio icon is displayed in the tab in Chrome.
• Chrome does display the audio indicator if the browser itself is muted in the operating system.

How to enable audio muting in Chrome

You can enable audio muting in Chrome to add muting functionality to the audio indicator that Chrome displays when a site plays audio.

Tab audio muting UI control

When enabled, the audio indicators in the tab strip double as tab audio mute controls. This also adds commands in the tab context menu for quickly muting multiple selected tabs. – Mac, Windows, Linux, Chrome OS

Here is how that is done:

1. Load chrome://flags/#enable-tab-audio-muting in the browser's address bar.
2. Flip the preference to Enabled.
3. Restart the browser.

Once you have restarted Google Chrome, you may hover the mouse cursor over the audio icon of the tab and left-click on it to toggle the audio playback state between mute and unmute.

Audio playback muted

As of Chrome 64, hitting mute will mute all tabs of the site in question and not only the page of the site you clicked the audio icon on.

Controlling audio playback with Site Settings

While you can enable the muting controls in the tab bar of the Chrome browser to mute sites quickly, you may also use the audio controls of the browser's Site Settings.

The audio controls give you three options:

1. Block audio on specific domains or websites.
2. Block all audio on all sites, and whitelist on specific websites.

The first option is useful if you visit websites regularly that play audio that you want blocked. The second option suppresses audio on all sites but gives you options to whitelist audio on select websites.

Option 1: Block audio on specific websites

You may block sound on specific sites only in Google Chrome. The browser offers two options for that.

1. Load chrome://settings/content/sound in the address bar and add sites to the "muted" list by clicking on add, typing a domain name and selecting add again.
2. By clicking on the icon in front of the address in Chrome's UI, selecting Site Settings, and changing the "allow (default)" sound setting to "block".

Option 2: Block all audio and use whitelist to allow playback

You can configure Chrome to block audio on all sites by default. This mutes sound in the whole web browser but you may add sites to a whitelist to allow sound playback on those sites.

1. Load chrome://settings/content/sound in the Chrome address bar.
2. Flip the "allow sites to play sound (recommended)" switch so that it is set to "mute sites that play sound".

You may add sites to the whitelist by clicking on the add link next to allow. Just type the address of the site, e.g. https://www.youtube.com/ and the add in the prompt to add it to the whitelist.

Chrome blocks audio on all sites but on whitelisted sites. The browser displays a muted sound icon on tabs of sites that play audio, and displays another indicator in the address bar.

You may interact with the address bar icon to allow sound on the site by adding it to the whitelist.

Chrome displays two options when you click on the icon. If you want to allow playback, select "always allow sound on" and then done to make the change.
