Steps to fix audio and video out of sync error in Windows 10

However, sometimes it's not the problem with your computer or your browser that it's the streaming service you're using that's causing the audio-video problem.

However, for things within your control that you can fix, you can try solving the problem yourself.

1. Try these easy solutions first

Before diving into your PC and starting to change its settings, try these quick and easy fixes to see if they solve the problem:

1. Restart the computer. If you haven't shut down your computer in a while, try restarting it. This way you allow it to clear the cache and terminate some processes running in the background.
2. Restart the application. Try closing the media player and relaunching it if you notice the audio and video are out of sync. Alternatively, you can switch to another program.
3. Check how much system resources you are using. If you have too many applications running at the same time, it can cause audio and video lag. Open Task Manager and check CPU usage. This usually happens when you are installing a new piece of software, so it is better to wait until the installation is complete.

2. Run the audio debugger

Windows 10 comes with many built-in troubleshooting tools that you can use anytime you have a problem. If the audio and video are out of sync, you should give the Playing Audio troubleshooter a chance to fix the problem. Here's how you can do it:

Step 1: Open the Start menu and go to Settings.

Step 2: Click Update & Security > Troubleshoot.

Step 3: Select Additional troubleshooter.

Step 4: Click Playing Audio > Run the troubleshooter.

The troubleshooter will now scan your computer for any problems. Once problems are detected, the tool will automatically fix them.

The final step of reconfiguring speaker properties is to open the Enhancements tab and uncheck the Disable all sound effects option.

Now, click Apply > OK to save the new speaker settings and restart your computer.

4 . Restore default settings for playback device

If none of the solutions above helped you fix your audio problem, you can try restoring your playback device settings to default.

Step 1: Go to Speaker Properties as mentioned above.

Step 2: Open the Advanced tab.

Step 3: Click the Restore Default button.

Step 4: Restart the computer.

5. Update audio driver

Normally, Windows automatically detects and installs new updates using the driver library along with the Windows Update services. However, sometimes you need to update your system drivers manually. In this case, you can use Device Manager to fix any outdated or corrupted drivers.

If you want to disable Battery saver mode, go to Settings > System. From the menu on the left, open Battery. Then, turn off the switch under Battery saver.

Step 3: Click Change plan settings > Change advanced power settings.

Step 4: In the Power Options window, navigate to Processor power management > Minimum processor state.
