# No sound in the browser

_Sound that works elsewhere but not in your browser is nearly always one of four things, and all four are quick to check._

Use the [speaker test](https://www.test-webcamp.com/speaker-test.html) to check as you go. It generates tones directly in the browser, so it tests the exact path that is failing.

## 1. The tab is muted

Every major browser lets you mute an individual tab, and it is easy to trigger accidentally. A muted tab usually shows a small crossed-out speaker icon on the tab itself.

Right-click the tab and look for **Unmute site** or **Unmute tab**. In Chrome and Edge this setting is remembered per site, so a site muted months ago stays silent forever with no obvious cause.

## 2. The wrong output device is selected

This is the most common cause on a desktop. Windows and macOS both switch audio output automatically when a monitor, dock, headset or Bluetooth device connects. Audio then plays perfectly, somewhere you cannot hear it.

- **Windows**: Settings, System, Sound, and check the output device. HDMI monitors without speakers are a frequent culprit.
- **macOS**: System Settings, Sound, Output. Option-clicking the volume icon in the menu bar is a faster route.

**Check Bluetooth first if you use it.** A headset that is connected but idle can still be the selected output, sending your audio to a device sitting in a drawer. Disconnecting it forces audio back to the speakers immediately.

## 3. The app volume mixer is turned down

Windows keeps a separate volume level for each application, so your browser can be silent while everything else is fine.

1. Right-click the speaker icon in the system tray.
2. Choose **Open Volume mixer**.
3. Find your browser in the list and check its slider is up.
4. Confirm its output device is also set correctly, since the mixer allows a per-app output.

## 4. Autoplay is being blocked

Browsers block audio from playing until you interact with the page, to stop sites making noise unprompted. This is not a fault. If a video appears to play silently, click the page once and try again.

The speaker test on this site is triggered by a button press, which satisfies that requirement, so it is a reliable way to test whether audio works at all.

## Per-site sound settings

Chrome and Edge allow sound to be blocked per site. Open **chrome://settings/content/sound** and check whether the site appears under the blocked list. Firefox has a similar control under Settings, Privacy & Security, Permissions, Autoplay.

## Still nothing?

1. **Test outside the browser.** Play any local file. If that is silent too, the problem is system-wide rather than browser-related.
2. **Try another browser.** If audio works there, the fault is a setting in the first one.
3. **Restart the browser completely**, including any background processes.
4. **Check the physical volume** on speakers and headsets, which is independent of system volume.

## Common questions

Sound works in other apps but not my browser.

Check the per-app volume mixer on Windows, and check whether the tab or site is muted. Both are browser-specific and leave other applications unaffected.

How do I unmute a tab?

Right-click the tab and choose Unmute site or Unmute tab. In Chrome and Edge the setting is remembered per site, so it can persist long after you set it.

Audio plays but I hear nothing.

The output device is almost certainly wrong. Check your sound settings for an HDMI monitor without speakers, or a Bluetooth headset that is connected but not with you.

Why does video start silently?

Browsers block autoplay with sound until you interact with the page. Click once on the page and play again.
