Sound Delay on Roku TV? 5 Quick Fixes for Audio Out of Sync

Experience seamless streaming on your Roku TV with quick fixes for lip sync.

Our guide provides straightforward solutions to ensure your sound and visuals are perfectly in sync.

Why is My Roku TV Audio Out of Sync?

Are you suddenly faced with unsynchronized audio on your Roku TV? Below are several possible reasons why it happened:

1. Slow Internet Connection 

A weak internet connection can affect your streaming progress, causing either the video or the audio to lag. This lag can throw the video and audio out of sync. 

Several factors contribute to poor internet connection; there may be too many devices on your network, the router may be too far from your Roku TV, or your network provider could have poor service.

2. Volume Mode

There are audio settings embedded under the Volume Mode feature on Roku TVs. These settings automatically adjust the audio stream to fit users’ preferences. 

However, the audio adjustments under these volume modes may cause your audio stream to lag. The different volume modes include:

Night mode feature: 

This volume mode is responsible for adjusting sounds in different scenes. It automatically increases the volume level in scenes with whisperings and low-tone dialogues. 

Night Mode also levels out the volume in scenes with loud noises like explosions, high-pitched shrieks, and screams. If you’re a fan of horror movies, this volume mode will probably come in handy. 

Leveling: 

This volume mode keeps the volume on your preferred settings across multiple channels. So, even when you change channels, the volume settings stay the same as when you activated the Leveling mode.

Off: 

The Off mode is responsible for disabling current volume mode settings and returning your Roku TV to its original/default audio settings. 

3. Faulty App/Channel

A faulty or buggy channel can affect the playback quality of your media stream. One of the ways this loss of quality presents itself is through audio desynchronization.

If audio is unsynced on your Roku TV, try changing the channel or app you’re streaming on to see if the issue is the same across other channels or restricted to that channel alone. 

5 Solutions to Fix Audio Delay On Your Roku TV

Not every problem with your Roku TV requires you to seek professional help. With the help of a thorough guide, you can identify the causes of specific issues and fix them in an instant. 

This section contains easy solutions to unsynchronized audio resulting from any of the reasons discussed above. We’ll walk you through it.

1. Improve Your Internet Connection

There are several things you can do to strengthen your internet connection. They include:

Restarting Your Router

Consider restarting your router if your internet connection is weak, unstable, or completely unavailable. A restart fixes several fundamental problems, including overheating. 

Restarting your router can give it the speed boost it needs and allows it to reload and select the most robust network channel, plugging you into a much stronger internet connection. It also gives your router time to cool off and, simultaneously, helps clear the cache overloading the processor. 

Step 1: Unplug the router from its power source. 

Step 2: Give the router 30 seconds – or more – to cool off and clear its memory.

Step 3: Plug your router back into the power source, and after it reconnects to the network, check if the audio is still out of sync. 

Shortening the Distance Between Devices

If a restart does not fix your internet issues, consider the distance between the router and the Roku TV. The farther apart they are, the thinner your network stretches to maintain the connection.

Adjust the distance between both devices to 15 feet or less. 

Decluttering the Network

Remember that too many devices on your network can also stretch the connection bandwidth thin. If connected devices are not currently in use, disconnect them from the router network.

Changing the Ethernet Cable

If you are on a wired connection, check to see if your Ethernet cable is damaged or loose at the connection point. A damaged connector, broken cable, or low-quality cable can slow your internet connection.

Fix or replace the cable, depending on the issue.

2. Switch Off Volume Mode 

Disabling and reenabling Volume Mode can help reset or reboot your audio stream. If Volume Mode is already enabled on your TV, turn it off and then turn it back on.

Take the following steps:

Step 1: Ensure you are on the channel or app you are streaming from. 

Step 2: Press the Asterisk (*) button on your remote.

Step 3: Scroll to and select the Volume Mode option on the menu. 

Step 4: Select the Off option if a Volume Mode option is enabled.

Step 5: Most of the time, turning off Volume Mode fixes your audio sync. However, if you still want to use a Volume Mode setting, wait 30 seconds before turning it on again.

Note: Alternatively, you can access the Volume Modes settings from your Roku home screen. Press Home on the remote followed by Settings > Audio > Volume Modes.

3. Reinstall the App/Channel

Reinstalling the app or channel you’re streaming from can help reset it and eliminate any bugs that plagued the previous version.

Follow the steps below:

Step 1: Go to the Roku Home screen on your TV, scroll through the channels and highlight your target channel.

Step 2: Press the Asterisk (*) button to display the options.

Step 3: Select Remove Channel.

Step 4: Confirm your choice when the prompt comes up, and the app will disappear shortly.

Step 5: Restart the TV (power it off and on again). 

Step 6: Install the app/channel again from the Home screen.

Step 7: Click on the Streaming Channels option.

Step 8: Scroll through the list, select your desired channel and click OK.

(You can use the Search Channels tool at the bottom of the app list.)

Step 9: Select Add Channel.

Step 10: Press OK after the download completes. 

If the solutions above do not work for you, here are other things you can do to re-sync audio on your Roku TV

4. Restart Your Roku TV

This action can help rid the TV of bugs or corrupt files. 

Step 1: Power off your TV and unplug it from the power source. 

Step 2: Give the TV 30 seconds to cool off.

Step 3: Plug the power cable back in and switch the TV on. 

5. Clear the Cache

Cache data is a temporary memory file containing information on sites and channels that your device has previously visited. This information helps it access and navigate those sites faster.

Accumulated cache data can affect a device’s processing strength and speed. Follow the steps below to clear the cache data on your Roku TV. 

Here’s a shortcut to clearing your Roku cache:

Step 1: Turn on your Roku TV and stay on the Home tab.

Step 2: Press the Home button five times.

Step 3: Press the Up navigation button once.

Step 4: Press the Rewind button two times.

Step 5: Finally, press Fast Forward twice. 

About 10 to 20 seconds after completing these steps, your Roku TV will restart.
