Fix Audio/Video Out of Sync Problems on Netflix (All Platforms)

Netflix audio may get out of sync if Netflix settings (HD mode) or TV settings (like Match Frame Rate) are not properly configured. Moreover, the outdated OS of your device may also cause the issue at hand. The issue arises when streaming content on Netflix. The issue is reported on all major platforms like Windows, mobile devices, etc.

Netflix Audio Out of Sync

The audio delay on Netflix can be fixed by the solutions mentioned below but before that, power off your devices (like mobile, TV, & networking equipment). Then unplug the devices from the power sources & wait for one minute. Then power on the devices one by one and afterward, check if the Netflix is working fine. Also, check if the issue is not, in particular, in a show only. If it is, then most probably the issue is with the audio of that show. Also, it will be a good idea to have a look at how to fix the audio and video out of sync error on Windows?

1. General Workarounds:

Following are the workarounds reported by the users to temporarily solve the Netflix issue:

  1. Check if disabling charger warning in the system’s BIOS (if using a non-OEM charger) solves the issue.
  2. You may try another network like the Hotspot of your phone (or use a direct ethernet connection from the router) to solve the issue. You may also check if forgetting the Wi-Fi network & re-adding it solves the problem.
  3. Check if pausing, forwarding/rewinding, & playing the show/movie solves the problem.
  4. If the issue is with a browser, check if disabling adblocker for Netflix or using Netflix in another browser solves the issue.
  5. Check if trying different cables & ports of the devices (e.g., TV, a soundbar, etc.) fixes it.
  6. Check if audio works fine if a headphone is used.

2. All Platforms:

The audio out-of-sync issue of Netflix could be a result of an improper configuration of Netflix sound settings (like HD or Stereo). In this scenario, properly configuring the Netflix settings may solve the Netflix problem. Here are few workarounds you can apply to any device:

6. Smartphone Users:

6.1 Update the OS of the Device to the Latest Release

Netflix audio may not be in sync with the picture if the OS of your Mobile device is outdated (which may create incompatibility between the device & Netflix). In this context, updating the OS of your device may solve the problem. For elucidation, we will discuss the process for an iOS device.

  1. Firstly, back up the essential data & plug the device into a power source.
  2. Now connect to a Wi-Fi network & launch the iPhone settings.
  3. Then open General & tap on Software Update.
    Open General Settings of iPhone
  4. If an update is available, download the iOS update & install it.
    Tap on Software Update
  5. Once installed, reboot your device & check if the Netflix audio is working fine.

6.2 Reinstall the Netflix App

The Netflix audio may get out of sync if the installation of the Netflix app is corrupt. In this scenario, reinstalling the Netflix app may solve the audio issue. For elucidation, we will discuss the process for the Android app of Netflix.

  1. Launch the Settings of your Android device & open Applications.
    Open Apps in the Android Phone’s Settings
  2. Then tap on Netflix & open Storage.
  3. Now tap on Clear Cache & afterward, tap on Clear Data.
  4. Then confirm to clear the data & hit the back button.
  5. Now tap on Uninstall & confirm to uninstall the Netflix app.
  6. Once uninstalled, reboot your phone & upon reboot, reinstall the Netflix app to check if the audio issue is resolved.

If that did not do the trick, then check if enabling Do Not Keep Activities in the Android Developer Options sorts out the Netflix issue.

7. Windows Users:

7.1 Update System’s Windows and Drivers to the Latest Release

Netflix audio may get out of sync from the picture if the system’s Windows and drivers are outdated (which may create incompatibility between them). In this context, updating the system’s Windows & drivers may solve the audio out-of-sync issue.

  1. Manually perform an update of the system’s Windows and make sure no update is pending to install.
    Check for Windows Updates
  2. Now update the system’s drivers (especially, the graphics drivers). Make sure all the drivers are applied in the Device Manager, especially, the chipset drivers. If your OEM has an update utility (like Nvidia GeForce Experience), use that utility to update the system’s drivers.
  3. Once Windows and drivers are updated, check if the Netflix audio issue is resolved.

7.2 Disable Autoplay in Hardware and Sound Devices

Windows uses the Autoplay feature (since Windows 98) to play media (or launch the appropriate application) as per the content but this feature may impact the system’s ability to catch up with the advanced web applications (like Netflix) and thus cause the audio issue. In this case, disabling the Autoplay feature may solve the problem.

  1. Click Windows, type Autoplay, and open Autoplay Settings.
    Open Autoplay Settings
  2. Now uncheck the option of Use Autoplay for All Media and Devices and reboot your PC to check if the audio syncing issue is resolved.
    Disable Use Autoplay for All Media and Devices

7.3 Disable Fast Startup of the System

Fast Startup in Windows is used to boot the system quickly (by saving a state between hibernation and power off to the system storage device) but sometimes it may “overlook” some of the modules essential for the operation of the system’s audio and thus cause the audio out of sync issue. In this context, disabling the Fast Startup may solve the Netflix audio problem.

  1. Right-click Windows and open Power Options.
  2. Now, in the right pane, open Additional Power Settings, and in the next window, click on Choose What the Power Buttons Do.
    Open Additional Power Settings
  3. Then click on Change Settings That Are Currently Unavailable and, in the options shown (near the bottom of the screen), uncheck Turn on Fast Startup.
    Disable Fast Startup
  4. Now Save Changes and shut down (not restart) your PC.
  5. Then power on the system and check if the audio out of sync issue is resolved.

7.4 Change Default Format of the Sound Device and Disable Applications’ Control Over it

The Netflix audio out-of-sync issue may arise if the default audio format of the sound device is not properly configured or applications are allowed to control the sound device (which may conflict with the Netflix processing and thus cause the issue). In this case, disabling the applications’ control over the sound device may solve the Netflix issue. But before proceeding, check if disabling all other system’s sounds (like notifications, etc.) and only using Netflix sorts out the sync issue.

  1. Right-click on the speaker icon in the system’s tray and open Sounds.
  2. Now, head to the Playback tab and double-click on your sound device.
  3. Then steer to the Advanced tab and set the dropdown of Default Format to 24-bit, 192000 Hz (Studio Quality).
  4. Now apply your changes and check if the Netflix audio sync issue is resolved.
  5. If not, repeat steps 1 to 3 to open the Advanced tab of the sound device and uncheck the option of Allow Applications to Take Exclusive Control of This Device.
    Change Default Format to 24-bit and Disable Allow Applications to Take Exclusive Control of This Device
  6. Now apply your changes and reboot your PC to check if the Netflix audio is operating fine.

If that did not do the trick, check if downloading and installing DirectX solves the audio sync issue.

7.5 Set Performance Options to Let Windows Decide

The Netflix out-of-sync issue may arise if the performance options of your system are set to Best Performance (which may cause the system to low-prioritize the media/graphics applications/modules). In this case, setting the Performance Options to Let Windows Decide may solve the audio problem.

  1. Click Windows, type: Advanced System Settings, and open View Advanced System Settings.
  2. Now click on the Settings button (in the Performance section) and in the Visual Effects tab, select Let Windows Decide What’s Best for My Computer and apply the changes.
    Open Performance Settings in Advanced System Settings
  3. Then, hopefully, the Netflix audio will not be “out of sync”.
