Amazon Prime Video is one of the biggest streaming platforms out there right now, home to many beloved TV shows such as The Boys, Westworld, and many others. Despite its widespread acclaim, this does not mean Amazon Prime Video is immune to video and audio out-of-sync issues.

These problems happen when the sound and video don’t match up perfectly, causing the dialogue to lag behind or lead the action on screen. This mismatch can disrupt your viewing and lessen the enjoyment of your favorite shows and movies. So, fixing Amazon Prime Video audio sync issues is key to keeping your streaming experience smooth and enjoyable.

Part 1. Common Causes of Audio out-of-sync Issues

Audio and video sync issues on Amazon Prime Video can seriously affect your viewing experience. When the sound and visuals don’t line up, you might see the dialogue lagging behind the action or the audio leading the visuals. This mismatch can be annoying and take away from the enjoyment of your favorite shows and movies.

Here are some reasons why this might happen:

  • Network Issues and Buffering
  • Poor internet connection or network instability can cause buffering, which affects how audio and video are out-of-sync on Amazon Prime Video. When the video is delayed due to buffering, the audio may continue to play normally, leading to a noticeable mismatch.

  • Device-Related Problems
  • The device you’re using to stream Amazon Prime Video can impact audio and video sync. Issues such as insufficient processing power or hardware limitations can cause delays in either audio or video playback.

  • App-Specific Glitches
  • Sometimes, the Amazon Prime Video app itself may experience glitches that affect synchronization. Bugs or temporary issues within the app can lead to audio and video becoming out-of-sync on Amazon Prime Video.

  • Outdated Software or Firmware
  • Using outdated software on your device or an older version of the Amazon Prime Video app can lead to performance issues, including sync problems. Keeping your software and firmware up to date is crucial for smooth playback.

  • Problems with Specific Films or Series
  • Occasionally, the issue might be specific to certain films or series on Amazon Prime Video. These problems could be due to the file format or encoding used for those particular titles, causing synchronization issues during playback.

Part 2. How to Fix out-of-sync Audio on Prime Video Based on the Causes

Dealing with these common causes might seem overwhelming, but don’t worry—we have solutions for each issue. These tips should help fix video audio sync problems when streaming Amazon Prime Video on a variety of devices, including Apple and Samsung TVs, Fire TVs, Sony and Roku TVs, PCs/Macs, Android and iOS mobile devices, and game consoles.

Here’s how to fix out-of-sync audio on Amazon Prime Video based on various causes, applicable to all devices:

1. Check and Reconnect Your Internet

If the problem is with your internet, check your connection by running a speed test on your device. Simply visit Speedtest by Ookla and click on the “Go” button to check on your internet speed. If your connection is slow or unstable, try restarting your modem or router to help reduce buffering issues. If you can, switch to a different network, like a wired connection or another Wi-Fi network, to see if that improves the sync.

2. Restart Your Streaming Device

If you can, try watching Amazon Prime Video on a different device or browser to check if the issue persists. This can help you find out if the problem is specific to one device or browser. If the issue is with your device, restart your streaming device, smart TV, or computer. A simple restart can fix many problems, including video audio out-of-sync, stuttering, and black screens on Amazon Prime Video.

The process of restarting your device may differ depending on the type you have. Generally, you can restart your Smart TV by going to “Settings”, selecting “Device Preferences”, and then clicking “Restart”. This will turn your TV off and then back on.

After restarting, try to play Prime Video again. Make sure you’re not using the same account on multiple devices simultaneously, as you can only stream the same title on two devices at once. Also, check that any external device is connected to your display using an HDMI cable that supports HDCP 1.4 (for HD content) or HDCP 2.2 (for UHD and/or HDR content).

3. Update Your Amazon Prime Video App

Make sure you have the latest version of the Amazon Prime Video app installed. If you are watching on mobile, check for updates in the App Store or Google Play Store. Or, you can also try to clear the cache of the Amazon Prime Video app from your phone’s app settings.

To clear cache and data for any app on your Google TV, follow these steps:

  • Step 1: Press the Home button on your remote and go to "Settings".
  • Step 2: Select "Apps" and open "See All apps"
  • Step 3: Find and select the "Prime Video app"
  • Step 4: Choose “Clear cache” and confirm by pressing OK.

4. Re-Install the Prime Video App

If you're using a smart TV, streaming device, or set-top box, make sure you have the latest firmware installed. Updates are often released to fix issues and improve performance. Also, check that your device is compatible with the latest version of the app and any software updates. If the problem continues, try uninstalling the Amazon Prime Video app, then redownload and reinstall it, and sign in with your account again.

5. Contact the Amazon Prime Support

Check whether the sync issue happens with other movies or TV shows. If the problem only occurs with a particular title, it might be an issue with that specific file. This could mean the file itself has a problem, such as incorrect encoding or other errors. If other content plays correctly, then the issue is likely isolated to that one title.

If the issue continues with specific content, reach out to Amazon Prime support directly for help or report the problem. They can offer detailed troubleshooting advice or additional steps to resolve the issue.
