There’s nothing worse. You’re settled in for the series finale of Succession, ready to absorb every last drop of the Roy family’s Shakespearean venom. Logan’s ghost looms, Kendall is pacing, and then you see it. Shiv’s lips move, but the cutting remark arrives a split second late. The entire rhythm is off. That pristine, high-stakes tension evaporates, replaced by a jarring disconnect. If you’ve ever wondered How To Fix Audio Delay On Tv, you’re not alone. This isn’t just a minor glitch; it’s an immersion-shattering problem that can ruin the most meticulously crafted television. But don’t throw your remote at the screen just yet. We’re going to get this sorted out, together.
What’s Really Causing That Annoying Audio Lag?
So, why is your TV’s audio out of sync with the picture in the first place? Think of it like a race between two runners: your video signal and your audio signal. In a perfect world, they leave the starting block and cross the finish line—your eyes and ears—at the exact same time. However, modern TVs do a ton of processing on the video signal to make it look crisp, vibrant, and stunning. They upscale resolution, smooth out motion, and enhance colors. This processing takes time, like a runner stopping for a water break. The audio signal, being much simpler, often doesn’t need these breaks and sprints ahead, arriving at your speakers or soundbar first.
This creates the dreaded lip-sync issue. The video has fallen behind the audio. While a few milliseconds are unnoticeable, anything more becomes the digital equivalent of watching a badly dubbed foreign film. The problem can originate from your TV, your soundbar, your cable box, or even the streaming service itself. Our mission is to find the culprit and restore cinematic harmony.
The Quick Fixes: Your First Line of Defense
Before we start diving into complex settings menus, let’s try the simple stuff. You’d be surprised how often the classic “turn it off and on again” approach works wonders.
- Power Cycle Everything: This is step one. Turn off your TV, your soundbar or AV receiver, and your streaming device (Apple TV, Roku, etc.) or cable box. Unplug them all from the power outlet. Wait a solid 60 seconds—no cheating. This allows the internal components to fully reset. Plug everything back in and turn it on. This can often clear a temporary glitch causing the sync issue.
- Check Your Cables: A loose or faulty HDMI cable can absolutely cause audio-visual chaos. Ensure your HDMI cables are securely plugged into both the TV and your external devices. If you’re using an older, beat-up cable, consider swapping it for a new, high-quality one. For advanced setups, especially those using eARC for Dolby Atmos, a certified Ultra High-Speed HDMI cable is a must.
- Change the Channel or App: Is the delay happening everywhere, or just on one channel or streaming app? Switch to a different channel or try watching something on a different app like Netflix or YouTube. If the problem disappears, the issue likely lies with the original broadcast or app, not your equipment.
How to Fix Audio Delay on TV by Diving into Settings
If the quick fixes didn’t do the trick, it’s time to roll up our sleeves and venture into the settings menus. This is where you’ll find the most powerful tools to solve the problem for good. The exact names and locations of these settings vary between brands like Sony, Samsung, and LG, but the principles are the same.
Navigating Your TV’s Audio Settings
Your TV’s audio menu is your primary command center. Grab your remote and look for a settings button (often a gear icon). From there, navigate to Sound or Audio. You’re looking for an option that might be called:
- AV Sync Adjustment
- Lip Sync
- Audio Delay
- Match Screen and Sound
This setting allows you to manually add a delay to the audio signal, effectively telling it to “wait” for the video to catch up. It’s usually a slider measured in milliseconds (ms).
How to use it:
- Find a scene with plenty of clear dialogue. A news broadcast or a talk show is perfect for this.
- Open the AV Sync/Audio Delay setting.
- Slowly adjust the slider. If the audio is happening before the video (the most common issue), you’ll want to increase the delay.
- Watch the person’s lips closely as you make adjustments. Your goal is to get their lip movement to match the sound of their words perfectly. It takes a bit of patience, but this is often the most effective fix.
What If You’re Using a Soundbar or Home Theater System?
Using an external audio system like a soundbar or a full AV receiver adds another layer to the equation. In this case, the audio signal often travels a different path than the video, making sync issues more likely. The good news is that most modern soundbars and receivers have their own audio delay settings.
“Modern video processing is a double-edged sword,” notes media technology consultant Dr. Alistair Finch. “It delivers breathtaking 4K and 8K images, but that computational power introduces latency. The challenge for home theater setups is ensuring the audio path, which is often more direct, is perfectly timed with the heavily processed video. This is why manual sync controls have become an essential feature.”
You have two main options here:
- Adjust on the Sound System: Check the settings on your soundbar or AV receiver first. They often have a more granular and effective sync adjustment tool. Use its remote to access the audio menu and look for the same “Audio Delay” or “Lip Sync” option.
- Adjust on the TV: If your sound system doesn’t have this feature, use the TV’s setting as described above. Just make sure the sound is actually playing through your external system when you make the adjustments.

Don’t Forget About Your Source Device
Sometimes, the TV and soundbar are perfectly in sync, but the signal they’re receiving is already messed up. Your cable box, game console, or streaming stick could be the real culprit.
- Streaming Devices (Roku, Apple TV, Fire Stick): Dive into the audio settings of the device itself. Some, like the Apple TV, have automated wireless audio sync tools that use your iPhone’s microphone to calibrate the timing. Others may have a manual adjustment.
- Cable/Satellite Boxes: These boxes are notorious for sync issues. Check the audio settings menu for any sync or delay options. A simple reboot of the box can also often resolve the problem temporarily.
- Game Consoles (PlayStation 5, Xbox Series X): Game Mode on your TV is crucial. This mode drastically reduces video processing to minimize input lag, which also helps keep audio in sync. If you’re experiencing delay while gaming or using a console’s streaming app, ensure Game Mode is enabled.
When the Content Itself Is the Problem
Have you ever noticed that the audio sync is perfect on Netflix, but a little off when you’re watching a live football game? Sometimes, the problem isn’t with your gear at all, but with the broadcast or the stream itself.
Live broadcasts are particularly susceptible to this. The signal goes through numerous stages before it reaches you, and timing errors can creep in along the way. Similarly, a specific movie or show on a streaming service might have an encoding error in its audio track. If you’ve tried everything and the issue is isolated to one specific piece of content, the best you can do is report it to the service provider and wait for them to fix it on their end. Think of it like a glitch in the Matrix—you can’t fix the code from the outside.
Frequently Asked Questions (FAQ)
Why is my TV audio out of sync only on one app, like Netflix?
If the audio delay only occurs on a single app, the issue is almost certainly with the app itself or the specific content you’re watching. Try updating the app, clearing its cache through your TV’s settings, or simply restarting your TV. If the problem persists, it may be a known bug that the developer needs to fix.
Can a bad HDMI cable really cause audio delay?
Yes, absolutely. A low-quality or damaged HDMI cable can struggle to transmit the massive amount of data required for modern video and audio, leading to errors and timing issues. Using a certified High-Speed (for 1080p/4K) or Ultra High-Speed (for 4K@120Hz/8K) HDMI cable is a smart investment.
How do I fix lip-sync on my Samsung TV?
On most modern Samsung TVs, you can find this setting by going to Settings > Sound > Expert Settings > Digital Audio Output Delay. From there, you can use the slider to adjust the timing until the audio and video are perfectly synchronized.
What is the difference between HDMI ARC and eARC?
ARC (Audio Return Channel) allows audio to be sent from your TV back down the HDMI cable to a soundbar or receiver. eARC (Enhanced Audio Return Channel) is the next generation of this technology. It has much higher bandwidth, allowing it to carry uncompressed, high-fidelity audio formats like Dolby TrueHD and DTS:X (the kind found on Blu-rays). eARC also has a mandatory lip-sync correction feature built-in, making it much better at avoiding these delay issues automatically.
Does ‘Game Mode’ on my TV help with audio sync?
Yes, it’s a huge help. Game Mode is designed to reduce video processing to an absolute minimum to create the fastest response time for gaming. A major side effect of this is that it greatly reduces the video’s “water breaks,” allowing it to keep pace with the audio signal much more easily, thereby preventing delay.
There you have it. The frustrating mystery of out-of-sync audio is rarely a sign of a broken TV. It’s a correctable timing issue born from the complexity of modern entertainment technology. By patiently working through these steps—from the simple power cycle to the fine-tuning of delay settings—you can restore the perfect rhythm to your viewing experience. So go ahead, reclaim that cinematic magic. You deserve to hear every whisper in The Bear‘s chaotic kitchen and every explosion in The Mandalorian at the exact moment you see it. Now that you know how to fix audio delay on TV, you’re back in control of your home theater.
