How to Fix Youtube Audio Out of Sync on Smart Tv?
4 Answers

When watching YouTube on a smart TV, nothing is more annoying than when the audio and video don’t match up. It can really mess up the whole experience. Let’s dive into why this happens and what you can do about it.
Why Does This Happen?
- Internet Connection Problems: This is a big one. If your internet is slow or keeps cutting out, your video might lag behind the audio. Streaming 4K videos, for instance, needs at least 25 Mbps. If your speed isn’t up to par, that’s probably your culprit.
- Software Issues: Sometimes, it’s just outdated software or weird glitches. If your TV’s firmware or the YouTube app is out of date, that can mess with the audio and video sync.
- Audio Settings: Messed-up audio settings on your TV can cause delays. Using the wrong output format or connecting incompatible devices can ruin the synchronicity.
- Bad Connections: Loose or damaged cables can cause problems too. Whether it’s wires between your TV and sound system or interference in the signals, it’s all problematic.
- Content Problems: Sometimes the issue lies in the video itself. Bad editing or encoding can result in sync problems.
How to Fix It?
- Improve Your Internet Connection:
- Test your speed on sites like Speedtest.net. If it’s below what you need, maybe it’s time to move that router closer or limit the number of devices on your network. You might even need to upgrade your internet plan.
- Connect your TV directly to your router with an Ethernet cable if you can. It’s more reliable than Wi-Fi.
- Restart Everything:
- Turn off your TV for about 30 seconds and then turn it back on.
- Force close the YouTube app and reopen it. On Android TVs, you can find the app in settings and hit “Force Stop” or “Clear Cache.” On iOS TVs, use the app switcher to close and reopen YouTube.
- Update Your Software:
- Check your TV settings for updates and install any that are waiting. An up-to-date system can fix bugs causing sync issues.
- Update your YouTube app from the app store on your TV.
- Check Audio Settings:
- Switch the audio output to PCM format. On Samsung TVs, go to the settings menu, find “Sound,” then “Expert Settings,” and set “Audio Format” to “PCM” instead of “Bitstream.” Look up the steps for other TV brands if you need.
- Try using the TV’s built-in speakers. If the sync issue disappears, the problem might be with your external audio device or its connection.
- Clear App Cache and Data:
- This can fix issues caused by accumulated junk. On Vizio TVs, use the home screen to find the YouTube app and clear its cache. On Samsung, go through “Settings” > “Apps” to do the same.
- Fix Your Connections:
- Check the HDMI cables or any other connections. Make sure they’re secure and undamaged. Replace any suspect cables.
- For Bluetooth devices, ensure they’re properly paired and consider switching to wired connections for stability.
- Test Other Content and Devices:
- Play different videos to see if the problem is specific to certain content. If only some videos are problematic, report them to YouTube.
- Connect another device like a phone or tablet to your TV and see if the problem persists. This can help you figure out if it’s the TV or the specific device.
If you’ve tried all this and still face issues, it could be time to contact YouTube support or your TV’s customer service. Have your TV model, YouTube app version, and a description of the problem handy for quicker assistance.
Summary
- Internet Troubles: Upgrade plans or switch to wired.
- Software Issues: Update TV firmware and apps.
- Audio Settings: Adjust to PCM.
- Bad Connections: Secure cables or switch to wired.
- Content Problems: Try other videos and report issues.
Audio and video sync problems can usually be fixed with some patience and tweaking. Hopefully, you can now enjoy your YouTube videos smoothly on your smart TV.

Dealing with audio sync issues on YouTube when you’re chilling in front of your smart TV can be a real headache. But don’t sweat it—there are a handful of reasons why your sound might be off, and easier-than-you-think fixes to get things back on track. Let’s jump into it!
Why the Audio Might Be Doing Its Own Thing
- Internet Blues: You know how it goes—a wobbly internet connection can mess with your streaming groove. YouTube needs that steady stream to keep your sound and visuals in harmony. If your Wi-Fi decides to have a bad day, expect a bit of chaos.
- Device Mood Swings: Not all smart TVs are created equal. Some might not be on the best terms with the YouTube app. If your TV’s a bit long in the tooth, it could be struggling to keep up with the latest features.
- Audio Twists: Sometimes, the way your TV’s set to spit out sound can throw things off. Fancier setups like surround sound might take their sweet time syncing up compared to plain ol’ stereo.
- App Quirks: Let’s face it, apps aren’t perfect. An outdated or glitchy YouTube app can be the culprit behind your timing troubles.
- Cache Clogs: Your YouTube app stores quite a bit of data, and sometimes, that cache turns into a mess, slowing things down and causing delays.
Quick Fix Ideas to Get You Back to Binge-Watching
- Rev Up Your Internet: If your Wi-Fi is acting up, try testing the speed, and aim for at least 13 Mbps for clear, HD vibes. Wired connections or shifting closer to the router can help stabilize things.
- Give Your TV a Nap: A good old-fashioned restart can work wonders. Just unplug it, wait a bit, then power it back up and see if that shakes the audio gremlins loose.
- Clear That Cache:
- Head to settings.
- Hop over to “Apps” or “Applications.”
- Select YouTube.
- Find the cache clearing option and give it a whirl.
- Keep YouTube in the Loop: Check for app updates in your smart TV’s app store. You wouldn’t want to miss out on those bug fixes and shiny new features, right?
- Change Up the Sound Settings:
- Go to the audio settings.
- Switch from surround sound to PCM—it’s simpler and usually better for keeping things synced.
- Try Different Clips: Before you get too far down the rabbit hole, play around with a few videos to see if it’s just one causing trouble.
- Fresh Start for the App: If all else fails, uninstall the app and give it a fresh install. This can sometimes wipe out any corrupted files messing things up.
- Go Nuclear—Factory Reset: If you’re still stuck, a factory reset might be your last resort. Just a heads-up, it’s going to wipe everything clean, so tread carefully.
Running through these steps might just save your TV-night. Don’t let sync problems ruin your chill time.

Sorting Out YouTube Sync Gaffes on Smart TVs: What’s Going Wrong & Fixes
Ever sat down to watch a killer YouTube video on your smart TV only to find the audio dealing you a delayed hand? Super annoying, right? It’s usually a mix of things causing the foul play, stuff like dodgy Wi-Fi or your TV not keeping up to speed. But it’s not all doom and gloom, let’s dig into why this happens and some fixes to get everything working smoothly again.
1. Your Internet Connection: The Usual Suspect
Why it’s a problem: Lame internet speeds can have your audio dragging behind the video.
What you can do:
- Give your internet a check-up: Hit up Speedtest.net to make sure it’s travelling fast enough. You want at least 5 Mbps for HD stuff and no less than 25 Mbps if you’re dealing with 4K.
- Buff up your Wi-Fi signal:
- Shift your router closer to your TV’s lair.
- Kick things that jam the signal, like microwaves or Bluetooth stuff, to the curb.
- A 5 GHz band will give you faster vibes than a 2.4 GHz one.
- Go old school with Ethernet: Hook your TV straight to the router with a trusty Ethernet wire.
- Give your router a refresh: Unplug for 30 seconds then plug back in – the tech equivalent of coffee I guess.
2. TV or Streaming Gadget Giving Up the Ghost
Why it’s a problem: Older models might lag behind because they can’t handle what you throw at them.
What you can do:
- Tidy up background apps: Close those sneaky apps hogging memory – more RAM, less drama.
- For Samsung lovers: Grab the Home button, track down those apps hanging around, and shut them down.
- For LG fans: Hit the Settings button and give that app cache a sweep.
- Power cycle your TV: Turn it off for a minute or two and let those glitches flow away.
- Consider an upgrade: Old TV dragging? Maybe snag a streaming buddy like Chromecast or Fire Stick.
3. Outdated Software Shenanigans
Why it’s a problem: A bugged-out YouTube app or TV software takes a toll on sync.
What you can do:
- Pimp out the YouTube app with updates:
- Head to your TV’s app haven (like Google Play Store or LG Content Store).
- Search for YouTube and hammer that Update button.
- Update your TV’s firmware too:
- Meander toward Settings > System > Software Update and get it done.
- Opt for automatic updates if you can, easier that way!
4. HDMI/ARC/eARC Playing Hard to Get
Why it’s a problem: Bad HDMI connections or external setups lagging, soundbars can be the villains.
What you can do:
- Investigate HDMI cables: Swap janky ones for crisp, high-speed HDMI 2.1 when dealing with hefty 4K content.
- Fiddle with audio sync settings:
- TV-wise: Find Settings > Sound > Audio Delay and mess with the slider.
- Soundbar/receiver-wise: Tap into their lip-sync feature.
- Try disabling HDMI-CEC: Features like Samsung’s Anynet+ or Sony’s Bravia Sync can play rough sometimes. Temporarily cut them off.
5. Audio Format Compatibility: Not Always Friendly
Why it’s a problem: Fancy audio types like Dolby Atmos can be a no-go if not compatible.
What you can do:
- Switch up audio output settings:
- On your TV, dive into Settings > Sound > Audio Format and give PCM or Stereo a shot.
- Turn off surround sound: In YouTube, opt for a lower audio quality like 720p, lightens the tech load.
6. Oh No – App Cache Bottleneck!
Why it’s a problem: Corrupted cache data in YouTube might mess up your playback.
What you can do:
- Clear that cache pronto:
- Android TV style: Track Settings > Apps > YouTube > Clear Cache.
- Samsung/LG approach: Uninstall, then roll in with a fresh install.
7. TV Sound Mode Headache
Why it’s a problem: Funky modes like “Movie” or “Sports” can lag your audio.
What you can do:
- Shift to “Standard” or “Game” mode: These tend to mellow out audio processing.
- Toggle off “Auto Volume” or “Dynamic Range Compression”: Check out the Sound Settings to silence these.
8. Factory Reset If You’re in a Bind
When nothing works, it’s factory reset o’clock:
- Hang onto important stuff—you don’t want to lose login deets.
- Head over to Settings > General > Reset.
- Reinstall apps and reset your preferences, takes a bit of time but worth it!
Still up against the wall?
- Flip through some other apps: Test if Netflix or Prime Video are struggling too to pinpoint the issue.
- Flag for backup: Reach out to your TV or YouTube’s support team—sometimes you need an expert.
By tackling these hurdles, you’re likely to fix up that sync snag and get your binge back on track.

Hey, so you’re having some trouble with YouTube audio getting out of whack on your smart TV, huh? Let’s get that sorted out!
1. Internet Acting Up? First things first—check if your internet’s playing nice. A patchy connection can throw the audio off beat.
2. Time to Power Down: Sometimes devices just need a little nap. Switch off both your TV and router, wait a minute or so, and then fire them back up. This little trick can often work wonders.
3. Update Patrol: Make sure no updates are lurking behind the scenes. Dive into the TV settings to hunt down system updates, and do the same for the YouTube app. Trust me, keeping everything updated can smooth out a lot of issues.
4. Tweak Those Audio Settings: Take a peek at your TV’s audio settings—look for tweaks like “Lip Sync” or “Audio Delay.” Play around with these until everything sounds just right.
5. Clear Out the Junk: Just like a messy room, an app packed with cache can act up. Head into the settings, find YouTube, and clear that cache! It’ll clear the cobwebs and could fix the mess.
6. Start Fresh with YouTube: If screw-tightening didn’t do the trick, maybe it’s time for a clean slate. Uninstall, then reinstall the YouTube app to clear out any corrupted bits.
7. External Speakers? Check ‘Em Out: If you’re rocking external speakers or a soundbar, make sure they aren’t the culprit. Switch to the TV’s speakers for a test run to zero in on the problem.
8. The Big Reset: Sometimes, all that’s left is a factory reset. Just know you’ll lose your settings and data, but it might save the day. Dig into the settings menu for this option if all else fails.
Still scratching your head? Have a gander at the manual or hit up the manufacturer’s support website for help specific to your TV model. And hey, don’t be shy to call customer service too—sometimes they’ve got the tidbits you need. Good luck getting your sound back in sync!
