Whether it’s a noticeable sound delay, a full lip sync issue, or a constant mismatch between video and audio, it can be incredibly frustrating—especially when you’re trying to enjoy your favorite show or a live game.

The good news? It’s fixable. This guide explains exactly what causes the YouTube TV audio out of sync problem and provides detailed, actionable solutions that work across every major device and platform. You’ll learn the root causes, fast troubleshooting steps, deep settings adjustments, and how to prevent the issue from recurring in the future.

What Causes Audio Delay on YouTube TV?

The problem of YouTube TV audio out of sync can stem from multiple sources, and understanding them is essential to finding the right fix. These audio delays don’t usually start randomly—they result from technical limitations, signal processing delays, or outdated components in your streaming setup.

Here are the most common causes:

• Slow or inconsistent internet speed: If your connection drops below 20 Mbps, it can cause buffer inconsistencies that lead to sound delay on YouTube TV—especially with live content or high-definition streams. If this continues, you may want to check for a possible YouTube TV outage.
  
  
• Outdated app or firmware: If your YouTube TV app, Smart TV software, or streaming stick is running old firmware, it may lack necessary performance or compatibility fixes, causing YouTube TV audio out of sync errors.  Visit our guide on how to activate YouTube TV to ensure a clean setup with the latest updates.
  
  
• Audio/video decoding limitations: Some TVs and devices cannot decode high-quality audio and video together smoothly, especially if you’re using Dolby Digital or surround sound settings.
  
  
• Bluetooth speaker or soundbar latency: Wireless devices can introduce noticeable audio lag, creating that common lip sync issue on YouTube.
  
  
• Resolution or refresh rate mismatches: If your device forces a resolution or refresh rate your TV doesn’t support natively, the sound may arrive faster or slower than the video. Read more about YouTube TV video format not supported.
  
  

All these issues, either separately or combined, can result in a sound and video mismatch.

Quick Checks Before Troubleshooting

Before diving deep into settings, there are a few quick checks that often solve YouTube TV audio out of sync without much effort. These easy steps can help isolate the problem or resolve minor sync issues immediately.

• Make sure your internet connection is at least 20 Mbps consistently. Streaming in 1080p or 4K requires a stable and fast connection.
  
  
• Restart the YouTube TV app completely. Fully close it, wait 10 seconds, and reopen.
  
  
• Try fast-forwarding or rewinding the video by a few seconds. This can often re-align the audio and video on the stream.
  
  
• Test playback on another channel. Sometimes, only one channel has a syncing issue.
  
  
• Use a different device to stream YouTube TV. This will help you determine whether the issue is device-specific.
  
  
• Confirm your TV or streaming stick is officially supported by YouTube TV. Unsupported devices are more prone to sync problems.
  
  

These steps can resolve or narrow down the root cause of the YouTube TV audio out of sync error quickly.

Step-by-Step Fixes for YouTube TV Audio Delay

Now that you’ve checked the basics, here are device-specific solutions to fix YouTube TV audio out of sync once and for all. These are tested fixes that address the real causes of sound lag and mismatch.

Fixes That Work on All Devices

• Force-close the YouTube TV app and restart it.
  
  
• Reboot your streaming device, Smart TV, or browser to reset memory and processes.
  
  
• Clear cache and app data on Android-based devices.
  
  
• Reinstall the YouTube TV app from scratch to ensure you’re on the latest version.
  
  

These universal steps solve many cases of sound delay on YouTube TV, especially when caused by temporary memory or software glitches.

Smart TVs (Samsung, LG, Sony, TCL, etc.)

If you’re watching on a Smart TV and experiencing YouTube TV audio out of sync, try the following:

• Navigate to your TV’s audio settings and manually adjust the audio delay or lip sync timing.
  
  
• Disable Game Mode or any image enhancement features that can introduce lag.
  
  
• Ensure both your TV’s firmware and YouTube TV app are fully up to date.
  
  
• Try switching the audio output format to “Stereo” or “PCM.”
  
  

These adjustments often resolve TV audio not matching video on native TV apps.

Streaming Devices (Roku, Fire TV, Apple TV, Chromecast)

Streaming sticks are also known for causing YouTube TV audio out of sync errors due to output format or bandwidth limitations.

Try the following:

• Change the audio output to PCM or Stereo instead of Dolby Digital.
  
  
• Disable Surround Sound or Dolby Digital Plus in your device settings.
  
  
• Use a different HDMI port or try a new cable.
  
  
• Lower your YouTube TV playback resolution to 720p to test if your hardware can handle syncing at lower loads.
  
  

Streaming devices often need fine-tuning to deliver synced playback, especially when using third-party apps.

Browsers (Chrome, Firefox, Edge)

If you’re using a browser and experiencing a lip sync issue on YouTube, follow these steps:

• Go to browser settings and disable hardware acceleration.
  
  
• Close other tabs or applications that might use up system resources.
  
  
• Switch to another browser temporarily to see if the issue persists.
  
  

Browsers use CPU and RAM heavily, which can desynchronize video and sound when under pressure.

Mobile Devices (Android and iOS)

For mobile users facing YouTube TV audio out of sync, the problem often lies in app performance or background processes.

• Restart your phone to free up memory.
  
  
• Clear cache and data for the YouTube TV app.
  
  
• Delete and reinstall the app to refresh all core files.
  
  

These steps usually fix sound and video mismatch caused by app-level bugs or memory overload.

Advanced Audio Sync Settings

Some advanced adjustments can permanently resolve YouTube TV audio out of sync problems. These settings are often hidden within your TV or streaming device but can be very effective.

• On Roku or Firestick, go to settings and enable or manually adjust Lip Sync Tuning.
  
  
• On Android TV, disable 5.1 surround sound in favor of Stereo/PCM.
  
  
• If you’re using Bluetooth speakers, switch to wired connections to eliminate transmission delay.
  
  
• Use Bitstream, PCM, or Pass-Through based on your speaker or soundbar support. Try all three to test what delivers best synchronization.
  
  

Using compatible and low-latency settings helps reduce future sound delay on YouTube TV streams.

When to Consider a Hardware Upgrade

Sometimes, no setting or fix can solve the persistent issue of YouTube TV audio out of sync. If you’re constantly dealing with sync issues, your hardware may be outdated or underpowered.

Look for devices or TVs that offer:

• Built-in Dolby Atmos or DTS Virtual:X for improved audio processing.
  
  
• 120Hz refresh rate for better video stability.
  
  
• Low-latency audio processors designed for streaming platforms.
  
  
• Example: TCL P755 Series includes audio sync enhancements and is optimized for modern streaming.
  
  

If you’re serious about seamless viewing, upgrading may be the long-term fix for eliminating lip sync issue on YouTube altogether.

Preventing Future Lip Sync Issues

Prevention is just as important as fixing current problems. To keep your YouTube TV experience smooth and fully synced:

• Update your streaming device and app regularly.
  
  
• Use wired connections for both internet and audio whenever possible.
  
  
• Reboot your router weekly to maintain connection quality.
  
  
• Clear app cache monthly to prevent data corruption.
  
  
• Avoid using Game Mode or video-enhancing features during regular streaming.
  
  

These habits will help you avoid another YouTube TV audio out of sync headache.
