How to Fix No Sound on YouTube

There are more than a few solutions you can try:

  1. Check your volume settings
  2. Check your browser
  3. Clear your browser cache
  4. Update your sound card driver
  5. Set your playback device
  6. Close running programs
  7. Run the Audio Troubleshooter
  8. Update Adobe Flash Player
  9. Check your security software

You can try these fixes sequentially as presented, or you can start with the ones you suspect to be the most likely solutions to your problem.

Without further ado, let’s get started.

But first, make sure that sound is not disabled on YouTube. In the bottom-left corner of your video, ensure that the speaker icon is not disabled. If it is, unmute it and then turn up the volume.

Fix 1: Check Your Volume Settings

The first thing you need to do is check your system sound settings and make sure that everything is in order.

Follow these easy steps:

  1. Click on the speaker icon in the right-hand corner of your taskbar. Ensure that the Mixer slider is turned up and not on mute.
  2. Now, right-click on the speaker icon and select Sounds.
  3. In the window that opens, click the Test button and see if you hear anything.
  4. Close the window and right-click on the speaker icon once again.
  5. Select Open Volume Mixer.
  6. Make sure that the sliders are turned up.

Fix 2: Check Your Browser

The sound issue might be caused by the web browser you are using. It could be having an issue with the installed extensions and plugins. This can cause the YouTube no sound issue to manifest itself.

Restart the browser and reload the video. This might help in resolving the problem.

Also, try playing the YouTube video on another browser. If you have sound, then it means that the problem is definitely browser-related. In that case, perform Steps 4 and 5 from the previous fix and see that the volume mixer slider for the particular browser is turned up.

Afterwards, carry out the suggestions below if you still don’t have sound.

Clear the Browser Cache:

If the volume settings are OK and there’s still no sound, clearing your browser cache and temporary files might help resolve the issue. Although this solution is not so popular, you may want to give it a try.

If you are using Chrome, follow these steps:

  1. Launch the browser.
  2. Click the Menu icon in the top-right corner of the screen.
  3. Select Settings.
  4. Scroll down to the bottom of the page and click the ‘Advanced’ drop-down to expand it and display more options.
  5. Scroll down to the ‘Privacy and Security’ category and click on ‘Clear browsing data.’
  6. Go to the ‘Advanced’ tab and select ‘All time’ under the Time range.
  7. Mark the checkboxes for the following items:
  • Browsing history
  • Cookies and other site data
  • Cached images and files
  • Site settings
  1. Now, click the Clear data button.

Uninstall and Update Your Browser:

If the problem still persists, then you have to consider uninstalling the browser and then installing the latest version.

Here’s how to uninstall a program on your PC:

  1. Press the Windows logo key + R combination on your keyboard to bring up the Run dialog.
  2. Type ‘appwiz.cpl’ in the text box and press Enter or click the OK button.
  3. In the ‘Uninstall or Change a Program’ window, locate your browser and right-click on it.
  4. Select Uninstall from the context menu and follow any instructions displayed on the screen.

You now have to install the most recent version of the browser. It is advisable to keep your browser updated. New updates contain patches and features that help boost performance and improve video and audio streaming.

Play your YouTube video and see if the problem has been taken care of.

Fix 3: Update Your Sound Card Driver

If you’ve tried playing your YouTube video on other browsers and notice that the no sound problem happens on all of them, you’ll need to update the drivers of your sound card. But first, make sure that it is enabled.

Follow these simple steps to get it done:

  1. Open the Run dialog. To do this, go to the Start menu and type ‘Run’ in the search bar. Then click on the option when it appears in the search results. Or to make things easier, just press the Windows logo + R combination on your keyboard.
  2. Type ‘devmgmt.msc’ in the text field and press Enter or click OK to open Device Manager.
  3. Locate ‘Sound, video and game controller.’ Click on the arrow to expand it.
  4. Now, right-click on your sound device (Realtek High Definition Audio, for instance). Click on ‘Enable device’ from the context menu if the option is present.
  5. If you find a yellow triangle that has an exclamation mark at the center on any of the listed devices, it means that there’s a problem with it.
  6. Right-click on it and select ‘Update Driver Software…’ from the context menu.
  7. You’ll receive a prompt. Select the option that says, “Search automatically for updated driver software.”
  8. After the update is complete, restart your PC and see if the YouTube audio problem has been resolved.

If the process fails to update the driver, visit the official website of your sound card manufacturer and download the driver from there (note the location where it is saved on your computer). Make sure that the one you get is compatible with your system.

Then follow these steps to install it:

  1. Go to Device Manager as already shown above.
  2. Click on ‘Sound, video, and game controller.’
  3. Right-click on your audio device and select Update driver from the context menu.
  4. When the prompt comes up, click on ‘Browse my computer for driver software.’

Here’s how to run the utility:

  1. Invoke the Run dialog by pressing the Windows logo + R combo on your keyboard.

Fix 7: Update Adobe Flash Player

Adobe Flash Player could be the culprit. It is a plugin that your browser uses to stream YouTube videos.

According to some users, the ‘No sound on YouTube’ issue began after they updated Flash Player. To find out if this applies to you, uninstall the updates and then check if that resolves the issue.

Here’s how:

  1. Press the Windows logo key + R combination on your keyboard.
  2. In the Run box that opens, type ‘appwiz.cpl’ and click Ok or press Enter.

  4. Locate Flash Player in the list and check the date it was last updated. If it is recent, click on it and select Uninstall.
  5. Now, try playing your video and see if the issue has been taken care of.

It could also be that Adobe Flash Player is corrupt or outdated. If you didn’t install an update initially, try doing so and see if that helps. Visit the official website to get it done.

Fix 8: Check Your Security Software

If the issue somehow persists after you’ve tried all the solutions presented above, then you need to check your security software (your antivirus program and firewall).

They might be interfering with Flash content, especially if they have a real-time scanning feature that restricts third-party flash content from establishing a connection.

Try disabling your antivirus program temporarily and see if the sound on your YouTube video will come up. If it does, contact the vendor of the program and report the problem to them. They should be able to tell you what to do.

You may also want to consider installing a different security program. We recommend Auslogics Anti-Malware. The tool is one of the best on the market and can even detect malicious items that your current antivirus may miss.

There you have it.
