Youtube TV Audio out of Sync

There you are, watching your favorite YouTube content creator on your Vizio TV, and you begin to notice what the content creator is saying is out of sync with what you are hearing. This is what Vizio and Samsung TV users have been experiencing when watching YouTube videos.

This problem could arise for a number of reasons. This could be brought on by the equipment that is being used and or your internet connection is the simple issue.

All of these possible difficulties will be discussed in this article, along with both easy and complex fixes for said difficulties.

Why is YouTube TV Audio Out of Sync

There are a number of possibilities as to why this issue has occurred, this could be caused by the TV you are watching the video on or it could be as simple as a loose connection.

Some Vizio TV models have a Lip Sync feature which is designed to adjust the audio of the program being viewed so that it matches the movement of the lips of the person talking on the screen.

This should be used if all content playing on your TV is out of sync with the video being shown.

However, there are times when even this feature will not be of help when you are experiencing issues with audio syncing. This can be very inconvenient and troublesome, though there are methods to fix this issue.

1. Problem with the Device You’re Watching

This problem with the audio not syncing up with what you are watching on your Samsung or Vizio TV could be caused by the device itself. As sometimes, issues can arise with the TV’s functions, such as its audio syncing.

If you haven’t also heard, technology giant Samsung is warning its customers to avoid discussing personal information in front of their new smart TV sets. The warning applies to viewers who control their sets using its voice activation feature.

It listens to conversations and may share any details it hears with Samsung or third parties. Even being as big as Samsung is, their TVs are still susceptible to experiencing problems.

Fix – Unplug TV For 60 Seconds Then Plug Back

When encountering issues with your Samsung or Vizio TV, it can sometimes be best to unplug it and plug it back in. This can help the TV essentially restart and restore errors that may be occurring within the system.

Inside every smart TV is pretty much a tiny computer that runs the programs and functions of the TV; so, when you turn it off and then unplug it, you are essentially rebooting it.

It is quite simple to; as all you have to do is, turn off the smart TV if it is on and then locate the power cord, trace it back to the outlet it is plugged into; then simply unplug it.

Wait at least 30 seconds before plugging it back in, then do so, and hopefully, this will help with the audio syncing issue.

2. Problem with the Show You’re watching

When encountering this audio syncing issue on your Samsung, Vizio or other smart TV, the problem could be with what you are watching.

The show you are attempting to watch could be faulty, damaged or have a bug. This means that it could have problems playing, issues with audio syncing, and or picture quality.

This could be the problem you are facing with your smart TV’s audio not syncing.

Fix – Change What You Are Watching

As stated before, the show you are attempting to watch could be faulty, damaged or have a bug. This can lead to the audio not syncing up with the show you are trying to watch or the show to not even playing.

What you can try to combat this problem is to change what you are watching, simply change the show and see if the problem persists; if it does persist, then it is most likely a different issue, if the audio syncs up and all seems well then the issue is with the show or its quality.

If a show’s quality is too poor, this can result in problems with viewing it, such as the audio not syncing, bad picture quality or bad audio.

Fix 2 – Try Playing the Same Content on a Different Device

Another tried and true way to test if it is a problem with the show you are attempting to watch; is to try playing it on another device, as this will tell if the issue is with the show, device or other. This will provide you with the information you need in order to proceed accordingly with fixing said problem.

3. Bad Internet Connection

In a world of almost constant connection to the internet, it can be easy to forget to check your internet connection. As this plays a key role in ensuring that everything you do online is indeed working properly and or is working at all; as all activities are done online require an internet connection, sometimes.

Some actions require a better connection in order to fulfill the action. So, whenever encountering issues with anything done online it is important to ask yourself, “Am I connected to the internet?”

Or “Is my internet connection strong enough for what I am trying to achieve?”. If either of the questions were answered with “No”, it is about time you check your connections.

Fix – Check Your Network

When dealing with problems derived from your internet connection, it is highly important to check the said network to ensure everything is running as it should be. Luckily, it is quite simple to do this. If your Vizio or Samsung TV is connected to the same network as your phone; you can check the network

quickly on your mobile device. Simply go to your phone’s settings, then proceed to ‘Network & Internet’, here you can check if your WiFi is working right.

Another valid option to check your internet connection is to see if your router is indeed connected. What you will have to do is, hop on your PC and follow these steps:

Step 1. Select the diagnostic tool: Ping.

Step 2. Type the IP Address/Domain name of the PC/server you want to ping the IP Address/ Domain Name.

Step 3. Click ‘Start to diagnose’. The following result indicates the connection is ok.

This is a sure-fire method to check that your router is connected.

Fix 2 – Restart Router/ Modem

A good method to ensure you are connected to the internet and that your router/modem is working properly is to restart them. As these devices serve a key role in supplying said WiFi internet connection.

Being as the modem is possibly the most important part. The sole purpose of the modem is to provide you with internet access.

If you were to only have one internet-connected device with an Ethernet port (such as a desktop computer), you could theoretically connect the modem directly to your computer with no need for a router.

As for the router; a router connects your devices to each other and, in hard-wired connection setups, to the modem. The router connects to your modem and then to your devices (laptops, smart TVs, printers, etc.) via either an Ethernet cable or, in the case of a wireless router, WiFi signal.

With all of this said let’s get restarting these devices, and let’s start with the formerly mentioned router. Follow these simple steps:

Step 1. Press the power button or unplug the power cord to your router.

Step 2. Turn it back on or plug it back into the electrical outlet and wait 30 seconds. Note: Always keep your router plugged in and turned on so that your TV can function properly. Restarting it or rebooting it, is the only time to turn it off.

Now, as for the modem, you can easily restart or reboot it by following these easy steps:

Step 1. Unplug the power and Ethernet cables from the modem.

Step 2. Wait 2-3 minutes for the modem to fully power off.

Step 3. Reconnect the power and Ethernet cables to the modem.

Wait for the Internet light to turn solid, then check if the internet is working properly. This should restore your internet connection to a functional quality.

Fix 3 – Use a Direct Network Connection

A good way to improve your internet connection is to use a direct network connection and if you are unfamiliar with what that means, here is a quick rundown.

A direct connection is a situation in which one computer is directly linked to another computer by a cable instead of a network. This might be using a crossover cable instead of going through an Ethernet switch.

This kind of connection is typically faster than using a network. Therefore, this will definitely help with your internet connection problem.

4. Bug in YouTube TV

It is very possible that the problem could be a bug in your YouTube TV, and if you are not familiar with what we mean by “bug”; A bug is an unexpected problem with software or hardware.

Typical problems are often the result of external interference with the program’s performance that was not anticipated by the developer. With that said, it is important to consider this possibility when encountering the audio not syncing up issue.
