Roku Audio and Video Out of Sync – How to Fix (# Ways Explained)

Imagine you are watching a horror movie on Roku and nights get longer and shadows creep in. You are ready to face terror while sitting on your couch but suddenly you notice that your video is lagging by the haunting sound of ghosts…..disappointed or maybe lost interest in the movie?

When you watch a movie or TV show or play a video game, the sounds you hear and the images you see are a combination of audio and video.

If the sounds from the Roku do not match the picture on the TV, there may be an audio/video or A/V SYNC error. This type of audio/video sync error is commonly referred to as a lip-sync error. This article describes how to fix Roku Audio and Video out of Sync errors and offers suggestions on how to correct their behavior.

Causes of the Roku Audio and Video Out of Sync error

  1. The cause of the problem is the basic utility connected to RokuTV. This feature may provide the best sound options, but many people think it’s the other way around.
  2. If a movie, TV show, or video game is not created correctly, it may contain an incorrect period, which can lead to an audio/video sync error.
  3. All content must be transferred to the device via the Internet, coaxial cable, satellite dish, or physical media. The loss or destruction of data during this process may result in incorrect audio and video signals.
  4. High-resolution video signals (such as 4K Ultra HD and HDR (High Dynamic Range)) require more data volume and are time-consuming to playback. As a result, the beep needs to be delayed for a long time after processing.
  5. Picture settings that affect video editing or audio settings that convert one audio format to another (also known as audio encoding) may contain audio/video sync errors or existing errors.

How to Fix Roku Audio and Video Out of Sync error

If you experience an A / V sync error while using the RokuStreambar on a TV or other connected device (game console, Blu-ray player, cable/satellite, etc.), please refer to the fixes below. Just follow the instructions below and the issue will be resolved immediately.

Method 1: Set the sound configuration to Stereo

Set the sound configuration to Stereo

In some cases, the simplest correction is the most effective method. So let’s start with the simplest repair.

If you see ads in the pop-up window, understand that syncing can cause errors. It is best to set the TV audio to “Stereo”. The problem will be resolved as soon as possible, we hope so!

Wonder, how to configure?

Step 1: Hit the home button present on the remote of your Roku device.

Step 2: Try to scroll down or up.

Step 3: Then open the Settings option> Click Audio/Sound.

Step 4: Then change the audio mode to stereo.

Step 5: Now, set the HDMI function to PCM-Stereo.

Roku devices with optical ports require HDMI and S / PDIF configuration for PCM-Stereo.

Method 2: Cross-check all links and connections

In most cases, the above solutions will work most of the time. If the problem still persists, check your internet connection. Low internet speeds and unstable connections can affect the quality of services, especially if you reside in-network restricted or remote areas.

The best way to test your connection is to use a website to check your download speed information. Also, the HDMI cable or power adapter can easily come off.

Power adapters

That sounds like an obvious solution, therefore, it is important to check that the HDMI cable and TV power cord are properly connected. If you use the Roku Streaming Stick +, you do not need a cable. Make sure your TV supports HDMI 2.0 or HDCP 2.2 connections.

Method 3: Remote Adjustments and configurations

If the above configuration does not work, you can quickly change the volume setting to correct the problem immediately. The result seems simple, but the changes are useful for many. All you have to do with the remote control is turn the volume function on and off.

Method 4: Press the star button (*) on the remote control

Imagine you are enjoying snacks while watching your favorite TV show. After switching to commercials, both audio and video are suddenly lost. There isn’t much sync for broadcast monitoring.

With our fixes, you won’t miss any important information about the scene as it requires simple adjustments to set it up correctly.

Try to solve through this:

Step 1: While playing content, you can access the volume settings by pressing the (*) button on the remote control.

Step 2: If your device has audio equalizer capabilities, turn it off.

Tadaaa…..done! Again, this setting seems very easy to work with but do not worry as it is suitable for many frustrated Roku users.

Method 4: Try to clear your caches and cookies

Cookies and caches are some information that is automatically saved by the browser when you visit any website. The clear option solves specific problems such as the readability of the site or the problem format.

Follow these simple steps to clear your caches

Step 1: Disconnect the Roku device and wait at least 5 minutes.

Step 2: Reconnection clears the cache and allows the machine to operate more efficiently.

It is recommended that you clear your cache regularly, whether you are facing any problems or not. Clearing the cache increases processing power and makes your machine run better. Taking a break and watching your favorite shows is no calmer than postponing the experience. Fortunately, all users generally report that one or more of these solutions continue to work.

Method 5: Check whether channel or device titles affected or not

If you have an audio/video sync error, stop playing the movie or TV show and try a different title. If you have played a video game and have an audio/video sync error, try a different title on the same console.

If you are sure that the sync error is related to a single title, the movie, TV show, or video game may have been created incorrectly or damaged. Try watching or streaming content from movies and TV shows on different channels with cable/satellite TV providers. Clean the disc with a natural medium or replace it with another.

If you have a lot of tracks experiencing an audio/video sync error, go to the next step.

Method 5: Switch the devices

If there are many titles, switch your TV to another device (with A / V sync error) and play movies, TV shows, and video games on the new device. If the sync error occurred only on the original device, restart the device.

Switch the devices

For multiple titles on one streaming channel, close the channel if A / V sync errors occur and check your content on other streaming channels.

The audio/video sync error disappears, the original stream channel is restarted and the same title is played continuously to determine if a sync error is a random event.

If multiple headers still affect multiple streaming channels, please contact your service provider and report the problem. If all devices are affected by an audio/video sync error, go to the next method.

Method 6: Configure TV settings

Try changing the TV settings as described below to fix the A / V sync error. For more information, see the online manual for your TV model or contact the manufacturer.

Some TV models have audio and video synchronization. It’s usually located in the Sound submenu of the TV options menu. If it’s a TV, change it to see if the A / V sync has improved. This feature is also known as “Listening Delay” and “Lip Sync”.

If you can hear the sound clearly before you see a photo, use the suggestions below.

Turn off advanced video editing, such as motion blur and noise reduction on your TV. These controls are usually located in the Video Options or Picture submenu under the Options menu.

If you hear loud noise after viewing your photos, try the tips below.

Set the TV’s digital audio output to PCM. This setting is usually found in the Audio submenu on the TV Options tab. If your TV has options, turn off the play mode.

Method 7: Adjust your bandwidth

If you are streaming in full resolution, you always need a better bandwidth. If you are considering a 2 or 4 KB stream, the bandwidth should be at least 25 Mbps. But even if your bandwidth is limited, you can always start and stop a movie or show and watch it after downloading.

 Adjust your bandwidth

If you don’t have enough bandwidth, it will usually slow down the video output. However, audio and video are downloaded at the same time. You may not feel confused if you watch a video that has a slow pause while watching the video.

Method 8: Replace Sound bar

If you’re using a recording device or soundbar and experience frequent audio or video delays, try removing the soundbar from the equation and setting your device to the built-in speakers. If it disappears, the soundbar may not be compatible with your Roku device.

Method 9: Try to stream in lower resolution

Set the TV to lower play mode or try watching lower resolution content. Game modes are designed to reduce picture quality and increase visual response time.

If this step resolves the issue, the issue is not with the Roku controller, but with the TV which does not support high definition video, and cannot decode high-quality audio signals.


As you can see, there are several reasons why audio, video, or both may not be as in sync while enjoying any movie or show on a Roku device. In some cases, a reset, fast forward, pause, and play may be enough to fix the problem. But if that’s not enough, you can do a lot on your own by following the guide Roku Audio and Video Out of Sync – How to Fix.
