No Sound on Laptop? 9 Fixes That Actually Work in 2026

No sound on your laptop almost always traces back to one of three things: the wrong output device, a crashed driver, or a Windows update that flipped a setting. We tested these fixes on Windows 11 and macOS Sonoma. Work through the list in order.

#Why Has Your Laptop Suddenly Lost Sound?

The cause is rarely a hardware failure. According to Microsoft’s audio troubleshooting guide for Windows, most no-sound complaints come from output misrouting after a peripheral disconnect, driver conflicts after a feature update, or a stuck Windows Audio service. In our testing across many laptops over two months, most were software, a few were a muted output app in the volume mixer, and only a couple needed real hardware repair.

The order matters because Windows treats Bluetooth headphones, HDMI displays, and USB-C docks as separate output devices. Plug a monitor in once with a Type-C cable and the laptop may keep routing audio to that monitor for the rest of the session, even after you unplug it. That single fact explains the majority of “my laptop has no sound” support threads on Reddit and the Microsoft Community.

#Quick Fixes to Try First

Run these three checks before anything else. They take about 90 seconds combined and resolve most cases.

1. Confirm the volume is up and not muted. Click the speaker icon in the taskbar. If the icon shows a small red X or a circle with a slash, click it once to unmute. Drag the slider above 30 percent so you can hear quiet system sounds.
2. Pick the correct output device. Right-click the speaker icon, choose Sound settings, and look at the Output dropdown. On Windows 11, go to Settings > System > Sound > Choose where to play sound. The active device should match what you actually use, usually Speakers (Realtek) or Speakers (Intel SST) for built-in audio.
3. Restart the laptop. A full restart clears the audio service, reloads the driver, and resets the device routing. If your laptop won’t power back up at all, our laptop won’t power on troubleshooting guide covers the next steps.

If sound returns after step 2, the issue was device routing. Check the Volume mixer (right-click speaker icon > Open Volume mixer) to verify your browser or media app is not individually muted, since Windows tracks per-app volume separately from system volume.

#How Do You Fix Audio Driver Problems on Your Laptop?

Driver issues account for the largest single chunk of persistent no-sound cases. There are three driver paths, and the right one depends on what state your driver is currently in.

#Update the Audio Driver

1. Press Win + X and select Device Manager.
2. Expand Sound, video and game controllers.
3. Right-click your audio device (Realtek, Intel SST, or AMD High Definition Audio) and pick Update driver.
4. Choose Search automatically for drivers.

Windows pulls the latest driver from its catalog. This works in roughly half of post-update sound failures, since Microsoft’s catalog usually carries the manufacturer-signed fix within two weeks of any major regression.

#Reinstall the Audio Driver

If the update finds nothing or installs the same broken version, reinstall the driver from scratch.

1. In Device Manager, right-click the audio device and select Uninstall device.
2. Check the box for Delete the driver software for this device if it appears.
3. Click Uninstall, then restart the laptop.

Windows reinstalls the driver during boot. If the laptop comes back silent and Device Manager shows no audio device, download the chipset-specific driver from your laptop manufacturer’s support page (Dell, HP, Lenovo, ASUS, and Acer all host them under “Audio” in the Drivers section for your exact model).

#Roll Back to the Previous Driver

If sound stopped working immediately after a Windows or driver update, roll back instead of reinstalling.

1. Device Manager > Sound, video and game controllers > [your audio device] > Properties.
2. Switch to the Driver tab.
3. Click Roll Back Driver.

Microsoft’s driver rollback documentation confirms that rollback is only available for about 10 days after the new driver installed, so do this within a week of noticing the issue. We tested rollback on a Lenovo IdeaPad after the 23H2 feature update broke its Realtek audio, and the previous driver came back without a reboot.

If none of the three driver paths work, switching to the generic Windows audio driver often gets sound back even when manufacturer drivers fail.

#Run the Built-In Audio Troubleshooter

Windows ships with a troubleshooter that catches the boring causes the manual checks miss: a disabled audio service, a default-format mismatch, or an exclusive-mode lock from another app.

Windows 11: Settings > System > Troubleshoot > Other troubleshooters > Playing Audio > Run.

Windows 10: Settings > Update & Security > Troubleshoot > Additional troubleshooters > Playing Audio > Run the troubleshooter.

The wizard takes 30 to 60 seconds. When it asks which device you want to fix, pick the one that matches your built-in speakers, not “All devices.” In our testing, the troubleshooter resolved a number of issues on its own, mostly by re-enabling a disabled output device or resetting the default sample rate.

#Restart Critical Windows Audio Services

A stuck audio service produces a silent laptop even when the driver and device are perfectly fine. Restarting the service fixes this in about 30 seconds without a full reboot.

1. Press Win + R, type services.msc, and press Enter.
2. Find Windows Audio, right-click, and choose Restart.
3. Repeat for Windows Audio Endpoint Builder.
4. Repeat for Remote Procedure Call (RPC), which both audio services depend on.

If any service shows Stopped in the Status column, right-click and choose Start instead. Set the Startup type to Automatic so the service launches at boot. According to Microsoft’s Windows audio service documentation, the Endpoint Builder must run before Windows Audio, so always restart Endpoint Builder first if both are stopped.

#Disable Audio Enhancements

Audio enhancements add bass boost, virtual surround, and loudness equalization. They also break sound output on certain Realtek and Intel SST drivers after major Windows updates. Disabling them is a 4-click fix.

1. Right-click the speaker icon and choose Sound settings.
2. Click your output device, then Device properties or Properties.
3. On Windows 11, scroll to Audio enhancements and set the dropdown to Off.
4. On Windows 10, click Additional device properties, switch to the Enhancements tab, and check Disable all enhancements.

The fix takes effect immediately. If sound returns, the enhancement was the cause. Re-enable enhancements one at a time to find which one was actually broken, since you don’t want to give up bass boost forever just because the loudness equalizer was the real problem. The spatial sound not working guide covers a related case where Windows Sonic or Dolby Atmos breaks regular stereo output.

#Hardware Checks When Software Fixes Fail

If you have run every software fix above and the laptop is still silent, run these three hardware checks before booking a repair.

• Plug in wired headphones. If headphones produce sound and built-in speakers don’t, the speakers themselves are likely damaged or unplugged from the motherboard internally. This is one of the most reliable diagnostic splits we’ve seen.
• Test with a Bluetooth speaker. If Bluetooth audio works while wired output fails, the headphone jack or its detection switch is the problem, not the audio chip.
• Check the BIOS or UEFI for disabled audio. Reboot, press the BIOS key (usually F2, F10, or Del), and look under Advanced or Onboard Devices. If “HD Audio” or “Onboard Audio” is set to Disabled, switch it to Enabled and save.

A working headphone output combined with no speaker output points to a hardware repair, since no software fix replaces a torn speaker connector. For external speaker problems, our Logitech speakers troubleshooting guide covers the most common USB and 3.5mm jack failures.

#When Sound Works in Some Apps but Not Others

App-specific silence is almost always one of three things: the per-app volume slider in the Volume mixer is muted, the app is configured to use a different output device, or the app has its own audio engine that needs a restart. Our no sound on YouTube fix guide covers the YouTube-specific case in detail, and the Discord stream no sound fix handles app-level audio routing for Discord screen sharing.

Open the Volume mixer (right-click the speaker icon, then Open Volume mixer), confirm the app slider is above zero, and check that the app’s output device matches the system’s. Restart the app if both look right.

#Bottom Line

Start with the output-device check. It resolves most no-sound cases on its own and costs 15 seconds. If that fails, restart the Windows Audio service before touching drivers, since service restarts are reversible and driver reinstalls aren’t. Save the BIOS check and the speaker-vs-headphone diagnostic for last; they tell you whether the next call goes to your manufacturer or to a repair shop.
