What to do when the TV Audio and Video out of Sync
TV audio and video not matching can be incredibly frustrating as mentioned above is a simple problem to fix, itโs actually very hard to fix without looking into the different components involved and their interconnections.
But luckily, fixing TV audio and video out of sync is not a big deal, especially if you look at the simplest solutions first.
Power reset TV
The first thing that you want to do when dealing with out of Sync issues is to reset the device.
TV delivers audio and video through several sources, which come from numerous devices.
Perhaps itโs a cable or satellite receiver, or maybe a DVD player.
And sure enough, the audio and video source may come from one of these devices.
If there are delays, it may be due to the TV itself not receiving the signal correctly.
Perform a quick power reset of the TV while adhering to model-specific safety shutdown directions.
Check for software updates
This applies to people who own a smart TV. The truth is smart TVs are like computers and the operating system can get bogged down with tasks as well as suffer from bugs that need repair or updating which is common due to video codex and other protocols that you wouldnโt normally know about as it all happens behind the scenes.
To be sure that your streaming is properly working, youโll want to check for software updates from the TV manufacturerโs website, this includes the use of any browsers, streaming devices and smart TV firmware and OS software updates.
These updates will often rectify bugs and help the device run more smoothly, thus eliminating audio and video out-of-sync issues. Alternatively, install new software updates through the TV menu.
With the latest updates, smart TVs can also improve their internet connectivity and speed, which will make it easier to stream content effectively.
Troubleshoot network connection
If you own a smart TV or other streaming devices, itโs possible that network connectivity is whatโs causing your audio and video to not match up.
Take steps to troubleshoot your connection. Perhaps the internet speeds are slow which causes buffering and in some cases causes the audio and video are not to sync.
If thatโs the case, you may have to reset your internet connection or change your router settings.
Enable AV Synchronization settings
For devices that donโt have a built-in option for AV synchronization, you can enable it through the settings.
This will ensure that devices linked to the TV get a chance to make adjustments to their outputted picture and sound.
With this option enabled, both audio and video will be synced properly and thankfully most modern TVs have AV sync adjustment features. Itโs designed to promptly fix any sound delays that may occur in the presence of any video lags and many times its automatic calibration.
To activate this feature, you need to go to your TVโs advanced options and then switch on the respective options.
On most TVs, this requires going into the audio menu and modifying the initial value so that it corresponds to your expectation.
Clear cache
Sometimes you need to clear the TVโs cache which is aย temporary memory area where stored content is temporarily stored for future viewing.
Sometimes, the information in this area gets corrupted and causes problems with audio and video being out of sync.
The common problem is when your TV does not have enough free memory to store all of its content, which should be resolved if you clear the cache.
Close background apps
Those background apps that are running on your TV may be the cause of intermittent audio and video out of sync.
You can open many background apps and close them before you start streaming videos.
This helps in making the process of accessing and playing media smoother.
Additionally, too many apps operating in the background tend to use up more of the available bandwidth.
As such, it is advisable to keep apps running in the background to a minimum.
It will also help to increase performance and reduce buffering.
Check for faulty connections
Sometimes the audio and video are not out of sync because of the TV itself.
Instead, there could be a problem with cables and connections that connect to the TV audio and video output ports.
In this case, youโll want to check every cable connection for damage using a continuity tester.
If you find faulty cables or connections, then simply replace them with new ones.
Final Thoughts
Having the audio on your TV out of sync with the video can be a very frustrating experience.
Itโs hard to see and listen to something at the same time.
Thankfully, fixing the issue doesnโt necessarily require a lot of technical knowledge or expensive hardware.
The first thing you want to do is check if the problem is coming from your TV or from the external devices connected to the TV.
If your television has a built-in option for AV synchronization, then youโll need to enable it.
