Audio and Video Out of Sync on Netflix? Here’s How to Fix It

You may have experienced a situation when you're ready to relax and enjoy your favorite Netflix show, but suddenly, the audio and video are out of sync. Maybe the dialogue doesn’t match the characters’ lips, or the sound is a few seconds ahead of the action.

While it’s super frustrating and can totally ruin the vibe, don’t be too stressed out about it! This problem is actually pretty common. In this article, we’re going to break down why this happens and more importantly, how you can fix it.

Part 1. Why is Netflix Audio and Video Not Syncing?

If you’ve ever noticed that the audio and video on Netflix aren’t lining up, there could be a few reasons behind it. Knowing these potential causes behind it can help you diagnose and resolve the issue more effectively. They range from network connectivity problems to device settings and even issues with Netflix content itself.

• Network Connection

One common reason is your network connection. Slow internet speeds or a weak connection can cause delays and buffering, which can throw off the sync between the audio and video.

• Problems with Device Settings

Sometimes, the issue lies in the settings on your TV or streaming device. If your audio settings aren’t correctly configured, it can lead to sync problems. It’s a good idea to check that your settings match the requirements of both your device and the content you’re watching.

• Outdated Firmware

Another possible cause is issues with your device’s hardware or software. Outdated firmware, incompatible hardware, or even corrupt files can all contribute to the audio and video falling out of sync.

• Problems with Netflix Content

Sometimes, though, the problem isn’t on your end—it could be with the content itself. Occasionally, a movie or show might have issues that affect audio sync, and these are typically resolved when Netflix updates the content.

• Streaming Quality

Finally, the quality of the video you’re streaming can also be a factor. Streaming high-quality video can sometimes overwhelm your internet connection or device, causing the audio and video to lose sync.



A quick and easy fix that might solve the problem is simply reconnecting your network. However, if the issue persists, you may need to dive a bit deeper into troubleshooting to get things back in sync.

Part 2. How to Fix Netflix Audio and Video Out of Sync on PC

If you’re watching Netflix on PC and dealing with audio and video being out of sync, here are a few simple fixes that might help.

1. Check Your Internet Connection

A slow or unreliable internet connection is often the main reason for video and audio not synced on Netflix. If your connection is being shared by multiple people, it can slow down, causing streaming problems. Netflix needs a minimum speed of 3 Mbps for basic streaming, and 5 to 23 Mbps for HD or Ultra HD.

To check your internet speed on your PC, press Win + R to open the Run dialog, type control, and press Enter. In the Control Panel, go to Network and Sharing Center and click Change adapter settings on the left. Double-click your Ethernet or Wi-Fi adapter to open its properties, and then check the connection speed in the Speed field.

2. Try a Different Browser

If your internet connection is solid but the issue persists, try switching to a different browser. Sometimes, your current browser might not handle Netflix well so it leads to the sync issues. For Windows users, Microsoft Edge is the best browser for Netflix as you can enjoy resolutions of up to 4K. For Mac user, it’s recommended to use Safari.

3. Turn Off HD Streaming

Streaming in HD can eat up a lot of bandwidth, and if your connection can’t keep up, it might cause the Netflix audio and video to fall out of sync. Turning off HD streaming is a quick fix. To do this, go to your Netflix profile, click on "Account" > "Playback Settings" and select a lower streaming quality that helps with the sync issue.

Part 3. How to Fix Netflix Audio and Video Out of Sync on TV

Apart from using a PC, you can watch Netflix on your TV. Watching Netflix on your TV should be a smooth experience, but sometimes the audio can fall out of sync with the video. If that happens, don't worry—there are also a few ways to fix it, depending on the type of TV you’re using.

If you’re streaming on Apple TV and the audio isn’t syncing with the video, the issue might be with your device or the content itself. Here are a few steps you can take to fix it:

3. Disable Dolby Digital

Sometimes, disabling Dolby Digital can help. Go to the Audio and Video settings on your Apple TV, find "Dolby Digital," and turn it off. After making these changes, check Netflix to see if the audio sync issue is resolved.
