Start with the simplest fixes first

A silent computer usually has one of three causes: the speaker is muted in software, the volume is turned all the way down, or the audio device isn't selected as the active output. Before you assume the hardware is broken, check these three things in order. Most speakers that seem dead are actually working fine—they're just not being sent any sound.

Open your system volume control. On Windows, click the speaker icon in the bottom right corner of your taskbar. On Mac, click the volume icon in the top right corner of the menu bar. If you see a muted symbol (usually a speaker with a line through it), click to unmute. If the volume slider is all the way to the left, drag it to the middle or higher. These two steps fix the problem about half the time.

Key Takeaways

  • Check the mute button and volume level in your system tray or menu bar before assuming hardware is broken.
  • Make sure your speaker is selected as the active audio output device in your sound settings, not a disconnected headset or HDMI output.
  • Restart your computer to reload audio drivers, which fixes many speaker problems without any manual troubleshooting.
  • Update or reinstall your audio drivers if restarting does not work, since outdated drivers often cause sound to stop working.
  • Test sound with a different app or website to confirm whether the problem is system-wide or limited to one program.

Verify the correct speaker is selected as your output device

Windows and Mac both let you choose which device receives sound. If you recently unplugged headphones, connected a monitor with built-in speakers, or plugged in a USB device, your computer may have automatically switched to that device instead of your main speaker. Open your sound settings and check which output device is currently active.

On Windows 10 or 11, right-click the speaker icon in the taskbar and select "Open Volume mixer" or "Sound settings." Look for the section labeled "Output" or "Advanced" and confirm your speaker is listed and selected. If you see a headset, HDMI output, or other device listed as active, click your speaker to switch back to it. On Mac, go to System Preferences, then Sound, then Output, and select your speaker from the list.

If your speaker does not appear in the list at all, it may not be recognized by your computer. Unplug it, wait ten seconds, and plug it back in. If it still does not appear, the speaker may need a driver update or the connection may be damaged.

Restart your computer to reload audio drivers

Audio drivers are the software that lets your operating system talk to your speaker. When a driver becomes corrupted or outdated, sound stops working even though the speaker itself is fine. A restart reloads these drivers without you having to do anything manually.

Save any open work, then shut down your computer completely. Wait at least ten seconds, then turn it back on. Once it finishes starting up, test your speaker by playing a video or opening a music app. If sound returns, the driver reload fixed the problem. If not, move to the next step.

Update or reinstall your audio drivers

If restarting did not work, your audio driver may be outdated or corrupted and needs to be updated or reinstalled. On Windows, open Device Manager by right-clicking the Start button and selecting it from the menu. Look for "Sound, video and game controllers" and click the arrow to expand it. Right-click your audio device (often labeled Realtek, Intel, or Conexant) and select "Update driver." Choose "Search automatically for updated driver software" and let Windows search for and install the latest version.

If Windows finds no update, right-click the same device and select "Uninstall device." Restart your computer. Windows will automatically reinstall the driver when it starts up. This clears out any corruption that an update alone might not fix.

On Mac, audio drivers are built into the operating system and cannot be updated separately. If restarting did not work, go to System Preferences, then Sound, and check that your speaker is still listed. If it has disappeared, the connection may be loose or the speaker may need repair.

Test sound in different apps to narrow down the problem

Before you assume your speaker is broken, test sound in at least two different places. Open YouTube or another video site in your web browser and play a video with sound. If that works, the problem is limited to one app or program, not your whole system. If YouTube has no sound either, the problem is system-wide and the steps above should fix it.

If only one app is silent, that app may have its own volume control or mute button. Check inside the app's settings or preferences menu. Some apps also have a separate volume slider in the Windows Volume mixer—right-click the speaker icon, select "Open Volume mixer," and look for your app in the list. You may need to unmute it or raise its volume there even if system volume is turned up.

Check for loose cables and physical damage

If your speaker is connected by cable, make sure the cable is plugged firmly into both the speaker and your computer. Unplug it, look for bent pins or visible damage, and plug it back in. If the cable is damaged, you will need a replacement cable or a new speaker.

For USB speakers, try plugging the cable into a different USB port on your computer. Some ports deliver less power than others, and a weak connection can cause the speaker to be recognized but produce no sound. If the speaker works in a different port, the original port may be failing.

If your speaker uses batteries, replace them with fresh ones. Low battery power can cause sound to cut out or become very quiet.

Disable audio enhancements that may be interfering

Windows includes audio enhancement features that can sometimes cause sound to stop working. On Windows 10 or 11, right-click the speaker icon in the taskbar and select "Sound settings." Scroll down and click "Advanced" or "App volume and device preferences." Look for any audio enhancement options and toggle them off. Restart your computer and test your speaker again.

Some computers also have audio software from the speaker manufacturer (like Realtek Audio Manager) that includes its own settings. Open that software and check whether your speaker is muted or disabled there. If you are not sure how to use it, try uninstalling the software entirely and using only Windows's built-in sound controls.

Frequently Asked Questions

Why does my speaker work in one app but not another?

The app that is silent may have its own mute button or volume control. Check inside the app's settings menu. You can also open Windows Volume mixer (right-click the speaker icon in the taskbar) and look for the app in the list—it may be muted or turned down there even though system volume is up.

My speaker is plugged in but does not show up in my sound settings. What do I do?

Unplug the speaker, wait ten seconds, and plug it back in. If it still does not appear, try a different USB port or cable. If it works in a different port, the original port may be damaged. If it does not work anywhere, the speaker may need a driver update or the connection may be broken.

I updated my audio driver but still have no sound. What is next?

Uninstall the driver completely, restart your computer, and let Windows reinstall it automatically. This clears out corruption that an update alone might not fix. If that does not work, test your speaker in a different app to confirm the problem is system-wide, not limited to one program.

Can a Windows update cause my speaker to stop working?

Yes. After a major Windows update, audio drivers sometimes become outdated or corrupted. Open Device Manager, find your audio device under "Sound, video and game controllers," right-click it, and select "Update driver." Let Windows search for the latest version and install it automatically.

My Mac speaker is not working. Do I need to update the driver?

Mac audio drivers are built into the operating system and update automatically with macOS updates. If your speaker is silent, restart your computer first. If that does not work, go to System Preferences, Sound, Output, and confirm your speaker is listed and selected. If it has disappeared, the connection may be loose or the speaker may need repair.
