How To Fix No Sound In Windows 10 April Update

Nothing makes a Windows update feel more dramatic than clicking play on a video and getting absolute silence in return. No ding. No music. No YouTube voiceover explaining how to fix the thing that is currently broken. Just a mute machine staring back at you like it pays rent. If your audio disappeared after the Windows 10 April Update, you are not alone, and the good news is that this problem is usually fixable without sacrificing your laptop to the tech gods.

The Windows 10 April Update, also known as version 1803, caused sound problems for some users by changing audio output settings, disrupting drivers, clashing with certain hardware, or nudging Windows into choosing the wrong playback device. In some cases, the issue was tied to Intel Smart Sound Technology. In others, Windows decided your monitor, Bluetooth device, or HDMI connection was the star of the show and sent audio there instead.

This guide walks through the most effective ways to fix no sound in Windows 10 April Update systems, starting with fast checks and moving into deeper repairs. Think of it as a calm, methodical rescue mission for your speakers, headphones, and sanity.

Why the Windows 10 April Update Can Kill Audio

When sound vanishes after a major Windows update, the cause is usually one of a handful of troublemakers. The update may install a generic audio driver instead of the proper one from your PC maker. It may reset your default playback device. It may disable or hide your speakers. It may also trigger a conflict with audio enhancements, HDMI audio, Bluetooth volume handling, or Intel Smart Sound Technology.

That last one is especially important. Some Windows 10 1803 systems experienced audio failures related to Intel Smart Sound Technology drivers. So if your sound disappeared right after the April Update and your Device Manager suddenly looks like a driver reunion gone wrong, that is a strong clue.

The upside is that no sound after a Windows update is often more of a software mess than a hardware disaster. That means your speakers are probably not dead. They are just being ignored, misdirected, or sabotaged by a driver with terrible judgment.

Start With the Quick Fixes First

1. Make Sure Windows Is Using the Right Output Device

This sounds almost too simple, which is exactly why it works so often. Windows 10 can switch audio output after an update, especially if you use HDMI, DisplayPort, Bluetooth headphones, USB speakers, docking stations, or a monitor with audio support.

Go to Settings > System > Sound. Under Output, make sure the selected device is actually your speakers or headphones. If Windows is trying to send sound to your monitor, your TV, or a disconnected headset, you will hear exactly nothing.

Then click Sound Control Panel, open the Playback tab, right-click your preferred device, and choose Set as Default Device. If your speakers are disabled, enable them.

2. Check Volume, Mute, and the Volume Mixer

Yes, this is the digital version of “is it plugged in?” But sometimes Windows updates change per-app volume settings, mute one output, or lower sound in the mixer while the main volume icon looks normal.

Click the speaker icon in the taskbar and verify the master volume is up. Then right-click the icon and open Volume Mixer. Make sure your browser, media player, and system sounds are not muted. If one app is silent while everything else works, the mixer is usually where the mystery lives.

3. Restart the PC

A full restart is boring advice, but it earns its place. Some update-related audio issues do not fully resolve until Windows finishes applying changes and reloads services. If you installed the April Update and immediately discovered silence, restart before doing anything more dramatic.

Run Windows Built-In Audio Repair Tools

4. Run the Playing Audio Troubleshooter

Windows 10 includes a built-in troubleshooter that checks common issues such as muted devices, disabled services, bad output selections, and driver problems.

Right-click the speaker icon in the taskbar and choose Troubleshoot sound problems. You can also go to Settings > Update & Security > Troubleshoot and run the audio troubleshooter from there. Let Windows do its little detective routine. It is not perfect, but it often catches the obvious stuff faster than humans do.

5. Show Disabled and Disconnected Devices

Sometimes your speakers are not gone. They are just hidden like a moody actor who missed their cue.

Open Sound Control Panel, go to the Playback tab, right-click in the blank space, and enable Show Disabled Devices and Show Disconnected Devices. If your speakers appear, right-click and enable them, then set them as default.

Fix the Driver, Because It Is Usually the Driver

6. Update the Audio Driver From Your PC Manufacturer

Here is one of the biggest mistakes people make: they trust Windows Update to install the best audio driver. Sometimes it does. Sometimes it installs a driver that seems technically alive but behaves like it is on vacation.

Visit your computer manufacturer’s support page and download the latest audio driver for your exact model. That means Dell for a Dell PC, HP for an HP machine, Lenovo for a Lenovo laptop, ASUS for an ASUS notebook, and so on. Install the driver, reboot, and test the sound again.

This matters because many laptops rely on custom audio packages built around Realtek, Conexant, Waves, Nahimic, or Intel audio components. Generic drivers may not fully restore speaker output, jack detection, microphone input, or enhancement controls.

7. Roll Back the Audio Driver

If the problem began immediately after the April Update or after a driver update that followed it, rolling back can be the fastest fix.

Open Device Manager, expand Sound, video and game controllers, right-click your audio device, choose Properties, then open the Driver tab. If Roll Back Driver is available, use it. Restart Windows after the rollback.

This step is especially useful when the newer driver is technically compatible but functionally terrible, which is a surprisingly common Windows tradition.

8. Uninstall and Reinstall the Audio Device

If rollback is not available or does not work, uninstalling the device can force Windows to rebuild the audio chain.

In Device Manager, right-click your audio device and select Uninstall device. Restart the computer. Windows will usually reinstall the driver automatically. If it does not, install the manufacturer’s downloaded driver manually.

This is one of the most reliable fixes for “No Audio Output Device Is Installed” errors after updates.

9. Repair Intel Smart Sound Technology Issues

If your system uses Intel Smart Sound Technology and the April Update knocked out your audio, this deserves special attention. On some systems, updating the Intel SST audio controller or switching it to the High Definition Audio Controller can restore sound.

Open Device Manager, expand System devices, find Intel Smart Sound Technology (Intel SST) Audio Controller, then choose Update driver. Select Browse my computer for driver software, then Let me pick from a list of available drivers on my computer. In affected cases, choosing High Definition Audio Controller can help restore output.

If you also see Intel SST errors, yellow warning icons, or missing Realtek output devices, reinstalling the correct OEM audio package after cleaning out the broken driver stack can make a big difference.

Fix Settings That Commonly Break Sound

10. Disable Audio Enhancements

Audio enhancements are great when they work and incredibly unhelpful when they do not. After an update, they can cause distortion, silence, or playback failures.

Open Control Panel > Hardware and Sound > Sound. Select your default playback device, click Properties, then open the Enhancements tab and disable all enhancements. If you do not see an Enhancements tab, check related advanced audio software installed by your PC maker.

Test the sound again after turning them off. If audio returns, congratulations: the “enhancement” was apparently enhancing silence.

11. Restart Core Audio Services

Windows sound depends on a few background services. If one of them gets stuck after an update, your speakers will sit there in total innocence while nothing happens.

Press Windows + R, type services.msc, and press Enter. Restart these services if needed:

• Windows Audio
• Windows Audio Endpoint Builder
• Remote Procedure Call (RPC)

Set them to start automatically if they are disabled.

12. Check HDMI, DisplayPort, and Bluetooth Devices

If your PC is connected to a monitor or TV, Windows may be sending audio through HDMI or DisplayPort instead of your built-in speakers. Likewise, if you previously paired Bluetooth earbuds or a headset, Windows may still prefer them even when they are not actively in use.

Disconnect unused Bluetooth audio gear, turn Bluetooth off temporarily, and switch the default playback device back to your speakers. If you use a monitor, remember that not all monitors have speakers, even when Windows proudly insists they do.

There was also a known Bluetooth volume quirk around Windows 10 version 1803, so if your Bluetooth audio is connected but wildly quiet or unresponsive to volume changes, that may be part of the puzzle.

When the Update Itself Is the Problem

13. Install Later Windows Updates

This sounds backwards, but it is often right. If a Windows update caused the issue, a later patch may fix it. Microsoft has released follow-up fixes for specific audio failures, including Intel driver-related problems.

Go to Settings > Update & Security > Windows Update and install all available updates. Then restart. If your sound broke because version 1803 introduced a compatibility bug, the fix may already be waiting in a later cumulative update.

14. Use System Restore

If audio worked perfectly before the April Update and every other fix fails, use System Restore to roll the system back to a restore point created before the problem began. This can undo broken drivers, settings changes, and update side effects without wiping your personal files.

Search for Create a restore point, open System Restore, and choose a restore point from before the update. It is not the first tool to use, but it is a very reasonable one when your system was happy yesterday and silent today.

15. Update BIOS and Chipset Drivers

If your speakers still refuse to cooperate, especially on a laptop, update the BIOS and chipset drivers from your manufacturer’s support site. OEM support articles often recommend this when audio issues linger after Windows updates because firmware and chipset software affect how the audio hardware communicates with the operating system.

This is not step one. It is step “we are now serious.” Still, on some systems, it is the missing piece.

What to Do If You See “No Audio Output Device Is Installed”

This message usually points to one of three problems: Windows cannot detect the audio controller, the driver is corrupt, or the system selected the wrong output path. Start by checking Device Manager for warning icons. Then update, roll back, or uninstall the audio device. If Intel SST is present, inspect it too. If your machine is a laptop, reinstall the manufacturer’s full audio package rather than relying on a generic driver.

Also check whether your internal speakers are disabled in BIOS or whether your monitor audio hijacked the default playback route. Weird? Yes. Common? Also yes.

A Smart Order for Troubleshooting

If you do not want to bounce randomly between settings menus like a confused pinball, use this order:

1. Restart the PC
2. Check output device and volume mixer
3. Set speakers as default playback device
4. Run the audio troubleshooter
5. Show disabled and disconnected devices
6. Disable audio enhancements
7. Restart Windows audio services
8. Update or roll back the audio driver
9. Uninstall and reinstall the audio device
10. Fix Intel SST if present
11. Install all later Windows updates
12. Use System Restore if necessary

That order saves time and prevents you from jumping straight to advanced fixes when Windows simply decided your monitor is now a speaker system.

Real-World Experiences With No Sound After the Windows 10 April Update

If you have ever dealt with no sound after the Windows 10 April Update, you already know the problem is not just technical. It is weirdly emotional. Audio is one of those computer features you do not think about until it vanishes, and then suddenly everything feels broken at once. Your music is gone. Your videos look like silent films. Your meeting app becomes a mime performance. Even the little Windows alert sounds disappear, which makes the whole PC feel slightly haunted.

A very common experience is this: the update installs, the computer restarts, and everything looks normal. Then you open YouTube, Spotify, Netflix, or a game, and there is no sound at all. The volume icon is not muted. The speaker slider is up. You plug in headphones and still get nothing. At that moment, most people assume the speakers died. In reality, Windows often just switched the output to HDMI, Bluetooth, or a ghost device that is not even in the room anymore.

Another familiar scenario happens on laptops with Realtek or Intel-based audio. The speakers stop working, but Device Manager still shows something that looks like an audio controller. That is where the confusion really kicks in. The hardware appears to be present, but the sound is still missing. Users often spend an hour changing volume settings before discovering that the driver is corrupted, mismatched, or replaced by a generic version that does not play nicely with the laptop’s custom audio package.

Then there is the “partial sound” experience, which might be the most annoying of all. Maybe Bluetooth audio works but the built-in speakers do not. Maybe system sounds work but games stay silent. Maybe headphones work only if they were already plugged in during boot. Maybe your monitor suddenly becomes the default audio device even though it does not have speakers. Problems like these make the issue feel random, but they usually point back to the same root causes: output confusion, driver conflicts, enhancement glitches, or update-side compatibility changes.

People also describe the April Update audio issue as a “fix one thing, break another” kind of problem. They reinstall a driver, and the speakers return, but the microphone disappears. They get sound back through headphones, but not through the internal speakers. They run the troubleshooter and Windows cheerfully announces that everything is fine while the laptop remains as silent as a library after finals week. That mismatch between what Windows reports and what the user actually hears is a big reason this issue feels so frustrating.

The encouraging part is that most users eventually solve it with a practical combination of steps: selecting the correct playback device, rolling back a bad driver, reinstalling the OEM audio package, disabling enhancements, or applying a later patch. In other words, the problem often looks dramatic but turns out to be repairable. It is less “your computer is doomed” and more “Windows took your audio on an unplanned detour.” Once you understand that, the troubleshooting process feels a lot less mysterious and a lot more manageable.

Final Thoughts

If you need to fix no sound in Windows 10 April Update systems, the most effective strategy is to stay calm and work in layers. Start with the obvious: output device, volume, mute status, and a restart. Then use the built-in troubleshooter, show disabled devices, and disable enhancements. After that, focus on drivers, especially if your machine uses Realtek, Conexant, or Intel Smart Sound Technology.

The most important takeaway is this: audio problems after a Windows update usually mean Windows changed something, not that your speakers suddenly gave up on life. With the right playback device, the correct driver, and a little persistence, you can usually bring the sound back without reinstalling the whole operating system or declaring war on your laptop.

And when the sound finally returns, maybe give your computer a respectful nod. It put you through chaos, yes, but at least now it can apologize with audio.
