Hearing no sound from your Windows PC can be frustrating, especially when everything appears to be connected correctly. One common cause is the “The Audio Service Is Not Running” error. This message usually means that an essential Windows audio service has stopped, failed to start, or is experiencing a configuration problem.
Fortunately, you can usually fix the issue without reinstalling Windows or replacing your sound hardware. In this guide, we will explain the most effective ways to solve the audio service problem and restore sound to your computer.
What Does “The Audio Service Is Not Running” Mean?
Windows relies on background services to manage audio playback and recording. The most important one is the Windows Audio service, which works with other components to deliver sound through speakers, headphones, USB audio devices, and other hardware.
When this service is stopped or unable to start, Windows may display messages such as:
- “The Audio Service Is Not Running”
- “No Audio Output Device Is Installed”
- “Audio services not responding”
- “The Windows Audio service cannot be started”
The problem can occur after a Windows update, driver change, system crash, software installation, or unexpected shutdown.
Common Causes of the Windows Audio Service Problem
Before trying advanced fixes, it helps to understand what may have caused the problem.
Common causes include:
- Windows Audio service is stopped
- Windows Audio Endpoint Builder is not running
- Corrupted or outdated audio drivers
- Recent Windows updates
- Incorrect audio device settings

- Click Apply and OK.
Restart Windows and check whether audio has returned.
3. Restart Your Computer
A simple restart can sometimes repair a temporary service failure.
Windows services can occasionally become stuck after installing updates, connecting new hardware, or recovering from a system crash.
Save your work, restart the computer, and test the audio again.
If the error keeps appearing after every restart, continue troubleshooting.
4. Run the Windows Audio Troubleshooter
Windows includes built-in troubleshooting tools that can detect common audio configuration problems.
On Windows 11:
- Open Settings.
- Select System.
- Choose Troubleshoot.
- Select Other troubleshooters.
- Find the audio or sound troubleshooter.
- Run the recommended diagnostic process.
Follow the instructions provided by Windows and allow it to apply automatic fixes when available.
The troubleshooter may identify disabled services, incorrect output devices, or driver-related problems.
5. Check the Selected Audio Output Device
Sometimes the audio service is working correctly, but Windows is sending sound to the wrong device.
For example, your computer may be using an HDMI monitor as the default output instead of your speakers.
Check your output device:
- Open Settings.
- Go to System > Sound.
- Look under Output.
- Select the correct speakers, headphones, or other audio device.
- Increase the volume and test the sound.
Also make sure the device has not been muted.
If you use a USB headset or Bluetooth speaker, disconnect and reconnect it before testing again.
6. Update the Audio Driver
A corrupted or outdated audio driver can prevent Windows from communicating properly with your sound hardware.
Update the driver:
- Right-click the Start button.
- Select Device Manager.
- Expand Sound, video and game controllers.
- Find your audio device.
- Right-click it.
- Select Update driver.
- Choose the option to search automatically for available drivers.
After installing an available driver, restart your computer.
You can also check your computer or motherboard manufacturer’s website for the latest audio driver specifically designed for your hardware.
7. Reinstall the Audio Driver
If updating the driver does not help, the existing driver may be corrupted.
Follow these steps:
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click your audio device.
- Select Uninstall device.
- Confirm the removal.
- Restart Windows.
Windows may automatically reinstall a compatible driver after restarting.
If it does not, install the correct driver from your PC, motherboard, or audio hardware manufacturer’s support page.
8. Check Disabled Audio Devices
An audio device may be disabled even though Windows recognizes the hardware.
Open Settings > System > Sound and review the available output devices.
You can also check Device Manager for devices showing a downward arrow, warning symbol, or other indication of a problem.
If an audio device is disabled, right-click it and select Enable device when available.
9. Restart Audio Services Using Command Prompt
If the graphical Services application does not solve the problem, you can restart the audio services through an elevated Command Prompt.
Open Command Prompt as administrator and run these commands individually:
net stop audiosrv
net stop AudioEndpointBuilder
net start AudioEndpointBuilder
net start audiosrv
After the commands complete, close Command Prompt and test your audio.
If Windows reports that a service cannot be stopped or started, note the exact message because it may provide clues about the underlying problem.
10. Run System File Checker
Damaged Windows system files can cause services to malfunction.
Windows includes System File Checker (SFC) to scan and repair protected system files.
Open Command Prompt as administrator and run:
sfc /scannow
Wait until the scan reaches 100 percent. Do not close the Command Prompt during the process.
If SFC finds corrupted files, Windows may automatically repair them.
Restart the computer afterward and check your audio.
11. Use DISM to Repair the Windows Image
If SFC cannot repair all detected problems, use the Deployment Image Servicing and Management tool, commonly known as DISM.
Open an administrator Command Prompt and run:
DISM /Online /Cleanup-Image /RestoreHealth
The process can take some time. When it finishes, restart the computer.
You can then run:
sfc /scannow
again to perform another system file check.
This combination can be useful when Windows components required by audio services have become corrupted.
12. Check Recent Windows Updates
If your audio stopped working immediately after a Windows update, the update or a driver change may be responsible.
Open:
Settings > Windows Update > Update history
Review recently installed updates and determine whether the audio problem started afterward.
Do not immediately remove an update unless you have confirmed that it is likely responsible. Before making major changes, consider checking for a newer Windows update or updated audio driver.
13. Perform a System Restore
If the problem started recently and System Restore is enabled, restoring Windows to an earlier restore point may help.
System Restore can roll back certain system files, drivers, and configuration changes without deleting personal documents.
Search Windows for Create a restore point, open the System Properties window, and select System Restore if an appropriate restore point is available.
Choose a restore point created before the audio problem began and follow the instructions.
14. Check for Hardware Problems
If none of the software solutions work, the problem may be related to hardware.
Check the following:
- Make sure speakers are powered on.
- Verify the volume knob on external speakers.
- Try another headphone or speaker.
- Test a different USB audio port.
- Disconnect and reconnect audio cables.
- Check whether Bluetooth headphones are connected correctly.
- Test the audio device on another computer when possible.
If multiple known-working audio devices fail on the same computer, the issue may be related to the PC’s audio hardware or motherboard.
How to Prevent Audio Service Problems
Once your sound is working again, a few simple habits can reduce the chance of similar problems returning.
Keep Windows Updated
Install Windows updates regularly, but also make sure important hardware drivers remain compatible with your system.
