How to Fix No Sound on Windows
Gone silent? Work through these checks in order — from volume and output device to drivers and audio services — to get Windows sound back.
Key takeaways
- Start with the obvious: volume, mute, and whether the right output device is selected.
- The built-in troubleshooter fixes a surprising share of cases automatically.
- A bad or missing driver is the most common deeper cause — reinstalling it usually restores sound.
- Test with headphones to tell a software problem from a dead speaker.
Few things are as abruptly frustrating as a PC that has gone silent. The good news is that the large majority of "no sound" problems on Windows are software settings or driver glitches, not broken hardware — and you can work through them in a logical order in a few minutes. This guide follows the same sequence Microsoft's own support recommends, from the quick checks to driver and service fixes, so you fix the cause rather than guessing.
First 60-second checks
Before anything technical, rule out the simple things, because they account for a huge share of cases. Check the volume is up and the speaker icon in the taskbar is not muted (click it and drag the slider). Make sure any physical volume knob, keyboard mute key or monitor volume is not turned down. If you use external speakers, confirm they are powered on and the cable is fully seated. Then restart the PC — a reboot clears the audio stack and genuinely fixes a fair number of glitches.
Test with headphones. Plug in any headphones or earbuds. If you hear sound through them but not the speakers, the problem is the speakers or their connection, not Windows. If both are silent, it is a software or driver issue — keep going.
Set the right output device
Windows often sends audio to the wrong place — an unplugged monitor, an idle HDMI port or a disconnected Bluetooth speaker. Click the speaker icon in the taskbar, then the arrow or device name next to the volume slider, and pick the correct output (for example "Speakers" or your headphones). On Windows 11 you can also go to Settings → System → Sound and choose the output device there. This single step resolves a large number of "no sound" reports, especially after plugging in a TV, dock or new headset.
Run the audio troubleshooter
Open Sound settings
Right-click the taskbar speaker icon and choose Troubleshoot sound problems, or go to Settings → System → Sound and scroll to the troubleshooter.
Let Windows scan
The troubleshooter checks for muted devices, wrong defaults, disabled services and common driver faults, and offers to fix what it finds. Accept its suggestions.
Apply and re-test
Play a sound or video after each suggested fix. Microsoft's automated troubleshooter resolves a meaningful share of cases without any manual work.
Update or reinstall the audio driver
If sound is still missing, the audio driver — the software that lets Windows talk to your sound hardware — is the usual culprit, particularly after a Windows update. Press Windows + X and open Device Manager, expand Sound, video and game controllers, right-click your audio device (often "Realtek" or "Intel Smart Sound") and choose Update driver → Search automatically. If that does not help, right-click the device, choose Uninstall device, then restart — Windows reinstalls a fresh driver on boot, which clears a corrupt one. For laptops, the cleanest driver often comes from your maker's support site (Dell, HP, Lenovo) rather than Windows Update.
Driver problems cause more than just audio faults. If you are updating drivers anyway, our guide on how to update drivers safely explains how to get them from the right source and avoid the dodgy "driver updater" tools.
Check the audio services
Windows audio relies on two background services. If they have stopped, nothing will play. Press Windows + R, type services.msc and press Enter. Find Windows Audio and Windows Audio Endpoint Builder, and make sure both show Running with a startup type of Automatic. If either is stopped, right-click and choose Start (or Restart). This fixes cases where sound vanished suddenly with no other changes.
Rule out the hardware
If software fixes have not worked, narrow down the hardware. Try a different pair of headphones or speakers, and a different port if you have one. Plug headphones into the front and back jacks on a desktop, since a faulty front-panel connector is common. For HDMI or DisplayPort audio to a monitor or TV, confirm the display actually has speakers and is selected as the output. If only one specific device is silent while others work, the fault is that device, not Windows.
If sound still fails
When every step above leaves you silent, a few options remain. Use System Restore to roll back to a point before the problem started, which undoes a bad update or driver change. Check Windows Update for a pending audio-related fix. As a last resort on a persistent, unexplained fault, an in-place repair install of Windows keeps your files while refreshing system components. And if a single device such as a headset or a desktop's audio jacks is dead while everything else works, you are likely looking at a hardware failure that needs a repair or replacement rather than more troubleshooting.
Frequently asked questions
Why did my Windows sound suddenly stop working?
The most common causes are an output device being switched (for example to an unplugged HDMI display), a muted volume, or an audio driver that broke after a Windows update. Work through the quick checks and the troubleshooter first, then reinstall the audio driver if needed.
How do I reinstall my audio driver?
Open Device Manager (Windows + X), expand 'Sound, video and game controllers', right-click your audio device and choose 'Uninstall device', then restart. Windows installs a fresh driver automatically on boot, which clears a corrupted one.
Why is there no sound after a Windows update?
Updates sometimes replace a working audio driver with a generic or incompatible one. Reinstall the driver from Device Manager, or download the latest audio driver from your PC maker's support page. System Restore can also roll back a problematic update.
How can I tell if it is a software or hardware problem?
Plug in headphones. If they produce sound but your speakers do not, the issue is the speakers or their connection. If both are silent, it is almost certainly a software or driver problem you can fix in Windows settings.
What are the Windows Audio services and why do they matter?
Windows Audio and Windows Audio Endpoint Builder are background services that the sound system depends on. If either is stopped, nothing plays. Open services.msc and make sure both are Running and set to start Automatically.
