Is the audio out of sync on your Netflix? It can be annoying to watch shows and movies on Netflix when users experience audio delays, where the sound either lags or comes before the video. Numerous factors, such as sluggish internet speeds, trouble connecting via Bluetooth, or malfunctioning apps or device settings, can cause this issue.
In this article, we’ll show you how to fix the Netflix audio out of sync issues on various devices. We’ll also show you how to download videos for offline viewing, which is a more reliable way to enjoy Netflix content without worrying about streaming errors.

Part 1. How to Fix Netflix Audio Out of Sync Easily?

The solutions are straightforward, and you’ll quickly discover what works for you if you test after each step. Try each of the solutions below, and after each one, test playback to see which one worked.
Solution 1. Check Your Internet Connection
One of the most common causes of Netflix audio delay is a weak or unstable internet connection. When your network speed slows down, the video frames may not buffer evenly, which can cause problems with syncing. Netflix suggests that for SD streaming, you need at least 3 Mbps, for HD streaming, you need at least 5 Mbps, and for 4K streaming, you need at least 25 Mbps.
If your internet speed is slow, try moving closer to your Wi-Fi router, switching to a wired Ethernet connection, or restarting your modem and router. Also, stop any downloads or streams that are happening in the background on other devices. Check Netflix again to see if the sound is back in sync once your internet is stable.
Solution 2. Change Device Audio Settings
Sometimes, the issue may not be with Netflix, but with the audio settings on your device. You can change the audio format to 44.1 kHz or 48 kHz on Windows by right-clicking the sound icon and going to Playback Devices. Turning off audio enhancements also helps stop delays in processing. Open Audio MIDI Setup on macOS and change the sample rate for your output device.
If you have a TV or soundbar, turning off surround sound or audio effects might get rid of extra lag. These little changes often bring sound and video back into sync.

Solution 3. Restart the Netflix App or Webpage
Sound can also go out of sync if there is a temporary problem with the Netflix app or your browser. In many cases, a simple restart will fix the problem. Close the Netflix app completely (not just minimize it), then open it again and try to play the video again. If you’re using a browser, try refreshing the page or starting the browser over again.
Solution 4. Use a Different Browser
If restarting doesn’t work, try using a different browser. Sometimes the problem is that Netflix’s video player doesn’t work well with certain browsers. For instance, Chrome might lag while Firefox or Edge plays the same content without any problems. If you only have sync problems in one browser, switching to another one is a quick fix while you look into the problem more.
Solution 5. Clear the Netflix App Cache
The Netflix app saves files in a cache over time to make loading faster. But if your cache files are broken or out of date, they can cause playback problems, like audio not syncing correctly. To clear the cache on Android, go to Settings, then Apps, then Netflix, and then Storage. To reset the cache on your iPhone, you need to uninstall and then reinstall the Netflix app.

Solution 6. Reconnect the Bluetooth Device
The wireless connection might be causing audio lag if you’re using Bluetooth headphones, earbuds, or speakers. Try unplugging and plugging back in your Bluetooth device, or use wired headphones to see if that fixes the problem. Also, make sure that the drivers for your Bluetooth on your PC or the firmware on your headphones are up to date. You can also reduce latency by getting your device and headphones closer together.
Solution 7. Turn Off Netflix HD Streaming
If none of the above works, try lowering the quality of the stream. To stream in high definition, you need more bandwidth and processing power. If your device has trouble, the audio and video can get out of sync. Go to your Netflix profile, then to Account, then to Playback settings, and choose a lower video quality (Standard or Low). This may mean giving up some visual clarity, but it usually makes playback more stable and gets rid of sync problems, especially on slower networks or older devices.
