- Audio latency may be due to hardware, drivers or settings of Windows 11.
- Update drivers, adjusting sound settings and disabling enhancements helps reduce lag.
- Bluetooth devices and advanced power options or BIOS significantly influence the synchronization of the audio.
Do you notice that the audio and video aren't synchronized in Windows 11? It's probably happened to you before: you're watching a movie, playing a game, or listening to music, and suddenly the sound arrives earlier or later than it should, completely ruining the experience. This type of audio latency problem is more common than you might think, and while it can sometimes be difficult to diagnose, here's a complete guide to adjusting latency and reducing sound delay on your Windows 11 computer.
In this article, you'll find all the tried-and-tested solutions recommended by experts and the community, from basic steps to advanced hardware and software configurations. We've also included tips for Bluetooth devices and specific tricks that have worked for other users. Let's get down to business and fix audio latency on your PC once and for all!
Why does audio lag occur in Windows 11?
The delay between audio and video is usually due to a variety of causes. One of the most frequent is the use of Bluetooth speakers or headphones . Wireless audio devices can introduce latency due to incompatibilities, poor hardware quality, or simply signal saturation. In fact, as reported by users in the Microsoft community, after continuous use many Bluetooth headphones begin to desynchronize and produce a noticeable delay.
But it's not the only culprit: outdated audio drivers , configuration errors, hardware acceleration issues, driver interference, or even incorrectly set BIOS options can all be behind the problem. Power plan settings and application configurations also play a role.
Sometimes, if you're just listening to music, you might not even notice, but in games or movies, the discrepancy is immediately apparent. Audio lag can even occur when using applications like Skype, streaming platforms , or web browsers, especially if your internet connection isn't stable or fast enough.
First steps to check system configuration
Before you dive into any major changes, review the basics:
- Check that all cables are properly connected and that there are no physical faults in the audio output device.
- Restart your PC and audio device (speakers, headphones, etc.) to rule out occasional blockages.
- Update Windows 11 to the latest version and make sure all updates are installed.
- If you use Bluetooth devices, pair them again: Remove the device in settings and then add it again.
- Change port USB or try on another computer to rule out hardware problems.
Specific solutions to reduce audio latency
1. Run the sound troubleshooter
Windows 11 includes an audio troubleshooter that automatically analyzes and fixes the most common problems. To run it:
- Right click on the Start menu and enter Configuration.
- Accede to System and then to Solve problems.
- Choose Other troubleshooters.
- En Play audio, click on Run.
When finished, Windows will tell you if it found any problems and if it fixed them, or at least give you clues about the cause.
2. Reinstall or change audio drivers
Sound drivers are key to avoiding latency. An outdated or incompatible driver can create significant lag between sound and image. There are three ways to address this:
- Sign in Device administrator (right click on Start).
- Expand the section Sound, video and game controllers.
- Right click on your audio device (for example, Realtek o Intel) and select Uninstall device.
- Restart your PC. Windows will automatically install the generic driver.
Some users achieve better results by manually installing the official driver from the manufacturer's website, while others opt for the generic Windows driver ( High Definition Audio Device ). For the best audio management results, you can also consult our guide on how to choose the best sound card.
Don't forget that if you use USB headphones or speakers, you must use the specific driver for that device, as the generic one often causes latency problems or simply doesn't work.
To keep everything up to date and avoid headaches, you can use automatic driver update tools , which download and install the correct versions of all audio components.
3. Disable exclusive control and exclusive application priority
In Windows' advanced sound settings, some options allow applications to take full control of the audio device to achieve lower latency. However, in practice, this can lead to conflicts:
- Right click on the sound icon (bottom right) and select Sounds.
- Go to the tab Reproduction and right click on your default device, then Properties.
- Enter the tab Advanced.
- Uncheck Allow apps to take exclusive control of this device y Prioritize applications in exclusive mode.
- Save the changes.
Disabling these options can improve latency and eliminate audio lag, especially if you're using multiple audio applications at the same time.
4. Restore the playback device to its default settings
If you have at any point changed the advanced settings or installed external sound packages, it's a good idea to return the audio device to its initial state :
- Accede to Sounds again from the audio icon.
- Eyelash Reproduction, right click on the default device and enter Properties.
- On the eyelashes Improvements y Advanced, click on Restore Defaults.
- Apply the changes.
This eliminates any settings that may be causing interference or incompatibility.
5. Change the audio format and disable enhancements
The default audio format and digital enhancements can also interfere with sound synchronization, especially if you have excessively high sample rates set. To adjust this and enable Game Mode in Windows 11 if you haven't already, see our recommendations.
Furthermore:
- Turn off the hardware acceleration in the browser settings menu.
- Clear cache and cookies.
6. Disable ErP and HPET in BIOS/UEFI
Some advanced BIOS settings (especially ErP and HPET ) can cause synchronization problems between the hardware and the operating system, resulting in skipping and delays in the sound:
- Balance Windows + I to open Configuration.
- Go to Recovery and select Restart now in Advanced Startup.
- Choose Troubleshoot > Advanced Options > UEFI Firmware Settings and restart.
- In the BIOS, locate the options erP o HPET and disable them. Save and restart.
Not all devices have these options, but if they do, it's a good idea to try disabling them to see if it improves audio latency.
7. Browser and Flash Player Settings
If you only notice audio delay in your browser , the problem might be related to your browser settings. Most browsers don't require Flash Player these days, but if you're experiencing specific issues with older websites, you can try installing it or switching to a different browser to see if the delay disappears.
Furthermore:
- Turn off the hardware acceleration in the browser settings menu.
- Clear cache and cookies.
8. Change the power plan to high performance
Power saving mode may prioritize efficiency over performance, which can sometimes affect audio quality. To adjust this and improve latency, also check out our guide to optimizing internet speed for streaming and gaming.
- Right click on the battery icon and select Energy options.
- Choose the plan High performance.
- If it doesn't appear, create a new one by selecting Create an energy plan and choose High performance.
- Set this plan as default.
This is especially important on laptops , but it also applies to desktop PCs. Make sure there are no other active profiles that might be limiting system responsiveness.
9. Manage Windows Updates
There are times when a Windows update introduces unexpected audio issues. Here's why:
- Accede to Settings > Update & Security.
- Check that you have all updates installed.
- If the problem appears after an update, consider Back to the previous version from Recovery.
10. Reinstall Windows as a last option
If the problem persists after trying all the solutions above, your system may be so damaged that only a clean reinstallation of Windows can restore proper audio performance. Back up your data first and follow the official guides to reinstall your operating system from scratch.
