Running Windows’ built-in Playing Audio troubleshooter resolves most computer sound issues automatically, restoring audio in minutes.
One moment the audio is fine. The next, nothing. No YouTube sound, no Spotify, no system chimes. On Windows 11 or 10, this happens more often than it should, but the cause is almost always a setting or driver that drifted out of place. This guide walks through the six fixes that actually work, in the order that works fastest.
What Causes Sound To Stop Working On A Computer?
Most sound failures on Windows PCs come from five sources: a wrong output device, muted audio in the volume mixer, a stopped Windows audio service, corrupted or outdated drivers, or audio enhancements that conflict with your hardware. In rare cases the onboard audio controller gets disabled in the BIOS after a system update. Physical problems — loose cables or a dead speaker — are the last thing to check, not the first.
Troubleshooting Sound Problems On A Windows Computer: The Fix Sequence
The fastest route to working audio is to move through these methods in order. Each one addresses a different failure point, and together they cover nearly every software-based sound problem on modern Windows machines.
| Method | What It Fixes | Effort Level |
|---|---|---|
| Playing Audio Troubleshooter | Driver and service configuration errors | Low |
| Verify Output Device | Wrong speaker or headphone selected | Low |
| Check Volume Mixer | Muted apps or system sound | Low |
| Restart Audio Services | Services stuck in a stopped state | Low |
| Update or Reinstall Drivers | Corrupted or outdated audio drivers | Medium |
| Disable Audio Enhancements | Processing conflicts with audio hardware | Low |
| Check BIOS and Physical Connections | Disabled onboard audio or loose cables | Medium |
Run The Playing Audio Troubleshooter
Windows includes an automated tool that scans for common audio problems and applies fixes without manual intervention. On Windows 11, go to Start > Settings > System > Troubleshoot > Other troubleshooters, find Playing Audio, and click Run. On Windows 10, the path is Start > Settings > Update & Security > Troubleshoot > Playing audio > Run the troubleshooter. When it finishes, the tool will tell you what it changed — most sound issues resolve at this step. Microsoft’s official guidance on troubleshooting audio problems recommends this as the first action for any sound loss.
Check Output Devices And Volume Mixer
Right-click the speaker icon in the taskbar and select Open Sound settings (or Sound on Windows 10). Under Output, make sure the correct device is selected — internal speakers, headphones, or external monitors with audio output. A common mistake: plugging headphones into a monitor that has no speakers, while the system routes audio to that monitor instead of the laptop’s own speakers. Next, right-click the speaker icon again and choose Open Volume mixer to verify that individual apps like Chrome, Spotify, or your video player aren’t muted.
Restart Windows Audio Services
The audio system relies on two background services that sometimes stop running. Press Windows + R, type services.msc, and press Enter. In the list, locate Windows Audio and Windows Audio Endpoint Builder. Right-click each one, choose Properties, set the Startup type to Automatic, and if the service status is Stopped, click Start. Restart your computer afterward.
Update Or Reinstall Audio Drivers
Right-click the Start button and open Device Manager. Expand Sound, video and game controllers. Right-click your audio device — typically “Realtek High Definition Audio” or “High Definition Audio Device” — and choose Update driver > Search automatically for drivers. If Windows finds nothing new, the driver may need replacement. Right-click the device again, select Uninstall device, check “Delete driver software” if the option appears, and restart the computer. This erases any corruption in the old driver.
If the restored driver still fails, right-click the device in Device Manager, choose Update driver > Browse my computer > Let me pick, then select High Definition Audio Device — the generic Microsoft driver — and click Next. This bypasses manufacturer-specific drivers that may be buggy and restores basic audio functionality.
Disable Audio Enhancements
Sound processing features like virtual surround, loudness equalization, and room correction can interfere with hardware and cause the output to go silent. On Windows 11, go to Start > Settings > Sound > Advanced settings and set Audio enhancements to Off. On Windows 10, go to Start > Settings > System > Sound > More sound settings, open the Playback tab, right-click the default device, select Properties, go to the Enhancements tab, check Disable all enhancements, and click OK. Audio should return immediately if enhancements were the cause.
Check BIOS And Physical Connections
If none of the software fixes worked, the onboard audio controller may be disabled at the firmware level. Restart the computer and enter the BIOS or UEFI setup — usually by pressing F2, F10, or Del during boot. Navigate to Advanced or Onboard Devices and confirm that the Sound Card or HD Audio setting is Enabled. If the system has no sound at all, physically check that speakers are plugged into the correct jack, cables are not damaged, and external monitors with audio output have their speakers enabled in the monitor’s own on-screen display menu. When the onboard audio hardware itself has failed, upgrading to a dedicated computer sound system bypasses the internal components entirely and restores full audio through external speakers.
Final Troubleshooting Quick Reference
When audio drops suddenly, use this symptom-based table to find the fastest fix for your specific situation.
| Problem | Quick Fix | Time Needed |
|---|---|---|
| No sound at all | Run Playing Audio troubleshooter | 2 minutes |
| Sound coming from wrong device | Select correct output under Sound settings | 30 seconds |
| One app has no audio | Unmute that app in Volume Mixer | 15 seconds |
| Audio cuts out or stutters | Disable audio enhancements | 1 minute |
| No sound after Windows update | Roll back or reinstall audio driver | 3 minutes |
| Monitor speakers produce no audio | Enable speakers in monitor’s OSD menu | 1 minute |
| All software fixes failed | Check BIOS for disabled audio controller | 5 minutes |
FAQs
Why did my sound stop working after a Windows update?
Windows updates occasionally replace audio drivers with newer versions that may not match your hardware perfectly. Open Device Manager, expand Sound controllers, right-click your audio device, choose Properties, go to the Driver tab, and click Roll Back Driver if available. If the option is grayed out, uninstall the device and restart to let Windows reinstall the generic driver.
How can I tell if my sound card is physically dead?
If no audio works from any output — internal speakers, headphone jack, and USB audio devices all produce silence — and the audio device does not appear in Device Manager even after showing hidden devices, the hardware may be damaged. Test with a USB sound adapter or external DAC. If that works, the internal sound card has likely failed and needs replacement or bypassing.
Can a virus cause no sound on my computer?
Yes, though it is uncommon. Certain malware drivers can block audio output or disable Windows Audio services. Run a full scan with Windows Defender or your antivirus of choice. After the scan completes, check the Windows Audio service in services.msc to ensure it is running and set to Automatic — malware sometimes stops this service to hide its own activity.
Will resetting Windows fix persistent audio problems?
A Windows reset that keeps your files often resolves deep audio issues by reinstalling the OS audio stack and default drivers. Go to Settings > System > Recovery and choose Reset this PC with the Keep My Files option. This removes third-party drivers and corrupted system files while preserving your documents and installed apps. Back up important data first as a precaution.
Why does my headphone jack work but not the built-in speakers?
This typically means the audio hardware and drivers are functional, but the system is stuck in headphone-detection mode. Check the Sound settings output device list and choose the internal speakers manually. If they do not appear, the headphone jack may have a stuck sensor pin — insert and remove the headphone plug several times rapidly to reset the mechanical switch inside the port.
