How to Fix Amazon Prime Video Audio Out of Sync – Effective Solutions

How to Fix Amazon Prime Video Audio Out of Sync

We’ve all been there. Settled in for a movie night, popcorn in hand, and the characters on the screen start moving their lips, but the words don’t quite match. It’s not a bad foreign film dub—it’s an audio sync issue.

No need to fret, dear reader, because I’ve got your back. Today, we’re talking about the world of audio-visual synchronization, specifically on Amazon Prime Video, explaining the steps to a flawless viewing experience.

The Issue Explained

The Issue of Prime Explained

Getting to the root of a problem is half the solution. With Amazon Prime Video, audio syncing issues can stem from various sources. In this section, we’ll get a clearer picture of what causes these issues and what signs to look for.

Causes of Desynchronization

  • Inconsistencies in Transmission: The prime cause is often an inconsistency in the transmission of data between the server (Amazon) and your device. Due to varying internet speeds or temporary server glitches, the video might load faster than the audio, or vice-versa.
  • Device Limitations: Sometimes, older devices struggle to keep up with the high-quality streams provided by Prime, leading to a lag in either video or audio.

Recognizing the Signs

The most glaring sign is, of course, when characters speak, and their words don’t match their lip movements. But there are other subtle indicators as well:

  • Background noises that don’t align with the scene.
  • Delayed sound effects, like a door slamming seconds after it’s shut.
  • Musical scores that seem oddly out of place.

Simple Solutions to Try First

Before diving into more complex solutions, there are some basic fixes that often resolve the issue instantly. They might sound obvious, but you’d be surprised how often they work!

The Pause-Play Trick

The age-old method of pausing a video and playing it again. This gives the application a moment to realign the audio and video. Here’s how you can try it:

  • Pause the video for about 10-15 seconds.
  • Hit play and check if the issue persists.

Refresh or Restart

A refresh can sometimes kick things back into alignment. If you’re watching on a web browser:

  • Simply press the refresh button or Ctrl + R (Windows) / Cmd + R (Mac).
  • For mobile or TV applications, close the app and restart it.

Tweaking Your Device Settings

Tweaking Your Device Settings for Amazon Prime

Sometimes, the issue is rooted a bit deeper within your device settings. But fear not! A few adjustments can put things right.

Checking Audio Settings

Your device’s audio settings might be interfering with the playback. To rectify:

  • Ensure that your device’s sound settings are set to ‘Stereo’ and not ‘5.1 Surround’ unless you have a supporting system.
  • If using external speakers or headphones, disconnect and reconnect them. Sometimes, the simple act of unplugging and plugging can do wonders.

Adjusting Playback Quality

Reducing the playback quality can alleviate sync issues, especially on older devices:

  • Go to Amazon Prime Video settings.
  • Select ‘Playback Quality’ and opt for a lower quality.
  • Play the video again to check synchronization.

Internet and Connectivity Solutions

Sometimes, despite our best efforts, issues persist. When that happens, here are your go-to solutions.

Update or Reinstall the App

Apps, like all software, receive periodic updates to address bugs:

  • Check if there’s an update available for the Amazon Prime Video app.
  • If the issue persists post-update, consider reinstalling the app.

Contact Support

Amazon’s customer support is there for a reason:

  • Reach out, explaining the issue in detail.
  • They might offer solutions you haven’t tried or escalate the issue if it’s on their end.

There’s always more than meets the eye when it comes to technology. If the standard procedures don’t cut it, here are some additional insights to refine your viewing experience.

External Hardware Checks

For those who have hooked their devices up to elaborate home theaters, the problem might not be with the device or app:

  • Ensure all cables connecting devices (like HDMI) are securely plugged in.

Why does my Amazon Prime Video audio get out of sync only when I stream on my phone?

Mobile devices, especially older models, may have limited processing capabilities compared to desktops or smart TVs. High-quality streams require robust processing, and if your phone struggles to handle it, it might lead to desynchronization.

Ensure your phone’s software and the Prime Video app are updated, and consider reducing playback quality for a smoother experience.

Can browser extensions or add-ons cause audio sync issues on Amazon Prime Video?

Yes, certain browser extensions, especially those related to video playback or ad-blocking, might interfere with the streaming process.

If you suspect an extension is the culprit, try disabling them one by one or use incognito/private mode, which usually disables all extensions, and check if the issue persists.

Will using a VPN affect the audio-video synchronization on Amazon Prime Video?

Using a VPN can potentially slow down your internet speed due to the added layer of encryption and the rerouting of data.  If the speed is significantly reduced, it might affect the stream’s quality and synchronization.

If you’re experiencing issues while using a VPN, try connecting to a server closer to your actual location or consider temporarily disabling it.

Are there specific audio formats supported by Amazon Prime Video that ensure better synchronization?

Amazon Prime Video generally optimizes audio for the best listener experience based on the device and connection. However, certain devices might handle formats like Dolby Digital or AAC better.

While Amazon adjusts formats automatically, ensuring your device supports these formats or has the latest audio drivers can lead to a more synchronized experience.

Could the audio sync issue be a problem with the original content and not on my end?

It’s possible, though rare. If a particular show or movie has an inherent sync issue, other users would likely report it, too.  Check reviews or online forums for any mention of such problems.

If many viewers report the same issue for specific content, it’s likely an error on Amazon’s end, and they’ll typically rectify it once aware.

How often should I update the Amazon Prime Video app to avoid such issues?

It’s recommended to set your apps, including Amazon Prime Video, to auto-update if possible. App developers regularly release updates to fix bugs and improve performance.

By keeping your app up-to-date, you minimize the chances of encountering synchronization and other playback issues. Checking for updates at least once a month can be a good rule of thumb.
