When the extension seems to do nothing, the problem is usually permissions, the wrong tab, or a page that does not play audio through a path Chrome lets extensions control. Work through the checks below before reinstalling.
Sound Booster targets media in the browser tab. If sound actually comes from another app, a system video player, or a different window, the slider will not change what you hear. Look for the speaker icon on the Chrome tab that is playing.
Open chrome://extensions, find Sound Booster, and ensure it is enabled. Open “Details” and check site access. Some setups require access on all sites, or at least on the domain you are using. If access is “on click,” open the extension popup on that page once so Chrome grants the tab permission.
A few players use special pipelines, protected streams, or separate processes. Others open media in an embedded frame where the extension needs permission on both the outer page and the frame’s origin. If one popular site never responds while YouTube does, note that difference — it is often a platform limit, not a broken install.
chrome://extensions and confirm Sound Booster is switched on.Following the order matters, because the first two steps fix most cases and cost almost nothing.
Chrome does not run extensions on some pages for security reasons. These include internal pages that start with chrome://, the Chrome Web Store itself, and certain built-in browser pages. If you try to boost a tab like that, nothing will happen, and that is normal behaviour rather than a fault.
If the page is open in an Incognito window, the extension only runs there when Allow in Incognito is switched on in its Details page. Also remember that each Chrome profile has its own extensions. A tab opened in a guest or work profile will not show an extension installed in your personal one.
Many learning platforms and news sites show video in an embedded frame that comes from another domain. In these cases the page you see and the player inside it can be treated separately by Chrome. If the extension works on one embed and not on another, the difference is often the frame’s origin or how the player outputs sound, not a broken install.
A site that worked last week may stop responding after it changes its player. Websites update often, and the way they play audio can change with them. If only one site fails and everything else works, try again after a few days and keep the details for a report.
If nothing above helps, send a short message through the contact page with the details below. It lets a person reproduce the problem quickly instead of guessing.
chrome://version and your operating system.Note the exact URL, whether the tab shows a speaker icon, and whether other sites work. That information matters more than a generic “it doesn’t work” report. You can reach us via Contact.
Check that you are adjusting the tab that is actually playing sound, that the tab is not muted, and that the page was reloaded after installing. Then check the site’s own player volume.
Learning portals often use embedded players from other domains or special streaming setups. YouTube’s standard player is simpler, so the difference points to the portal’s player rather than to your install.
That is a trade-off. All-sites access is convenient if you boost many pages, while limiting access to specific sites is more restrictive. Choose the option that fits how you listen.
Usually not. Permissions, the wrong tab and conflicts cause most problems. Reinstall only after the checks above, or if the extension is missing or disabled.
No. It works on audio playing in Chrome tabs. Sound from a desktop app has to be adjusted in that app or in the system volume settings.
