YouTube Audio Out Of Sync (8 Causes, Fixes)

YouTube is the most popular social media platform to share videos.

YouTube has videos about everything from DIY home improvement to fashion advice, and product reviews.

Sometimes, however, you might come across a video that has an out-of sync audio track.

This is a frustrating situation, especially if the video has to be watched to the end.

YouTube Audio out of Sync (8 Causes and Fixes).

Faulty Video

First, ensure that the issue is present across all YouTube platforms. It’s not just one video.

It’s impossible to change the fact that the video producers did not pay attention to how the audio and video were synchronized.

You can report the problem to YouTube for it to be addressed.

How to Fix

However, the solution is easy.

To ensure that it isn’t just one video, check out the other videos on YouTube.

Users have complained that YouTube videos sometimes seem to be out of sync when they are viewed in different ways. However, it is not evident in all videos.

To be 100% sure that the videos are correct, you can play multiple videos with different playback quality.

YouTube can be contacted if the problem is limited to one video.

Click on the YouTube profile picture, select Send Feedback and send a message.

2: Caching Issues

The browser cache keeps a copy of pages and videos you have viewed on your device, so they can load quickly if you need to return to the content.

Browser cache can sometimes be more trouble than it is helpful, especially if it gets too big.

Your browser can be slowed down by too much cached content.

How to Fix

Clearing your browser cache is the solution. It is very simple.

These are the steps to use Google Chrome

  1. Click the three dots in the upper right corner.
  2. Scroll down to Setting.
  3. Click on Clear browsing histories.
  4. Set an All-Time Time Range and make sure all three options are checked.
  5. Click on Clear data.

These steps will help you resolve the issue of out-of-sync on your phone.

  1. Go to the settings of your phone.
  2. Choose Apps.
  3. YouTube.
  4. Click on Storage to Cache.
  5. Click on Clear Cache.

Cause 3 – Hardware Acceleration

Hardware acceleration allows you to use visual content faster in browsers and other apps.

These browsers should be able to perform all tasks that require CPU resources.

Hardware acceleration allows them to use other hardware resources such as GPU to produce better-quality images and videos.

This feature could cause other issues on your system.

Hardware acceleration could be the reason your YouTube videos are not sync across browsers and web versions.

How to Fix

Switching to another browser is the easiest option. However, you can also use your preferred browser permanently by turning off hardware acceleration.

These steps will enable you to disable hardware acceleration

  1. In the upper right corner, click on the menu button.
  2. Select Settings.
  3. Click on Advanced to go to the left. Next, click System.
  4. When hardware acceleration is available, turn off

There are a few steps that Firefox uses to disable hardware acceleration.

  1. Go to menu > settings.
  2. Click on General> performance.
  3. To see the hardware acceleration option, uncheck the box beside Use recommended performance
  4. When is available, disable Use hardware acceleration

Similar steps can be followed for other browsers.

After you are done, restart your computer.

Cause 4: Audio Driver

Older or damaged drivers can cause problems on your device and pose a security risk.

It is possible that audios or videos appear out of sync, even if they are played on different platforms or software.

This is a sign that your audio drivers need to be updated.

How to Fix

To fix the problem, you can simply update the audio drivers.

There are many ways to do this, but the easiest is via Device Manager.

Here are some tips to update your audio drivers

  1. Right-click the Start Menu and choose Device Management.
  2. Expand Sound and video.
  3. Locate your audio device and click on it to open the Update Driver.
  4. Follow the instructions on screen to finish the update and restart your computer.

Cause 5 – Graphics Driver

Your graphics card is another piece of hardware that is crucial for producing playbacks with synced video and audio.

Although the hardware may be functional, outdated drivers can prevent your OS from properly communicating with it.

Graphic drivers can also suffer from the same issues as outdated audio drivers.

How to Fix

You can also update graphics drivers by following the steps above.

However, there is one important difference:

Go to device manager and expand Display adapters. Right-click on your graphics card and select the Update driver. You can also search for drivers automatically.

This isn’t the only way to upgrade your driver.

The manufacturer’s website has the most recent updates.

Make sure you download the compatible version for your system (64-bit vs 32-bit).

You can find out more about your system type in System Information.

Enter System Information into the Cortana search field on the taskbar, and click the first result.

You can now follow these steps after downloading the latest driver.

Only difference is that you need to select Browse My Computer for Drivers at the end.

Cause 6: Sound Enhancement

Audio Enhancement is a Windows function that enhances the audio experience.

This feature can be used to improve your audio quality depending on the sound card.

Ironically, however, this feature can cause audio-related problems.

To see if the issue of out-of-sync disappears, you could disable it.

How to Fix

Here are the steps to disable Sound Enhancement in Windows.

  1. Right-click the speaker icon in the upper right-hand corner. Select Open sound settings.
  2. Click on Sound Control Panel to the right of the window
  3. Click on the Playback tab within the new window.
  4. Select Properties.
  5. Check the Enhancements tab. Disable all enhancements.

Cause 7: Bluetooth Issues

img alt=”Wireless Bluetooth Speaker” src=””/>

Bluetooth headphones and speakers can sometimes add latency to your audio. This can cause annoying lags, although it is not something that is very common.

It is possible to either replace your device or use an AUX cable to connect it instead of Bluetooth.

This isn’t the best solution for convenience.

How to Fix

You can also play with your Bluetooth codecs to make it more efficient and useful.

The Bluetooth codec is how your computer encoded digital audio signals and sends them to an audio device.

You can eliminate audio delay by changing the default codec of your device to one with lower latency.

These are the most popular Bluetooth codecs that you will find on modern devices.

  • SBC. This codec is the default on most devices. Despite its simplicity, many users don’t find the audio quality to be sufficient.
  • AAC. Advanced Audio Coding is used on Apple devices, gaming consoles and YouTube.
  • aptX. This codec is the best for Bluetooth devices and comes in a variety of versions: aptX HD (low latency), aptX HD (high resolution) and aptX adaptive (adaptive). All codecs offered by Qualcomm are ideal for low-latency audio transfer.
  • Sony LDAC. This codec is best for high-res files because it transmits data more quickly than SBC.

You will need to follow different steps depending on the device to modify your Bluetooth codec.

A. Android

You must enable Developer Options before you can change your Bluetooth codec on Android devices.

To do so,

  1. Scroll down to About your phone, then open your device Settings.
  2. To activate developer mode, tap Build Number or Android version seven times.
  3. Go back to Settings. Open System. Then, go to Developer Option.
  4. You can open the Bluetooth audio code menu to choose a low latency codec from the available options.
B. Windows
  1. After you have connected your Bluetooth headphones/speakers to your Windows device, visit Control Panel> Audio.
  2. Double-click on your device to locate it.
  3. You can now check or uncheck whether the option allows you to use the codecs.
C. iOS

Apple devices don’t permit you to modify the Bluetooth codecs.

As previously mentioned, iOS default codec is AAC.

Apple devices can also be found that support SBC.

You can change the codec of an Apple device using some apps such as Sony’s songPal. This app is free and allows you to manage all your Bluetooth audio devices.

  1. After you have installed the app on your iPhone, launch it and then go to Settings.
  2. Select Bluetooth Codec from the menu.
  3. This page will allow you to find all codecs on your device, and then choose the one that best suits your needs.

Cause 8: Power Settings

Your computer’s power consumption is controlled by your power plan.

Its primary purpose is to conserve battery by turning off high-performance features and dimming screen brightness.

It can also impact how YouTube videos are played.

How to Fix

Windows 10 comes with three power options: high-performance, balanced and power saver.

By default, your computer is in balanced mode

You might be experiencing audio lags when you use YouTube. Check to make sure your computer is in power-save mode.

Sometimes, power saver mode can turn off important audio features which could cause unusual problems.

Try switching to balanced mode to see if the issue is solved.
