Fix No Audio Output Device Is Installed

The speaker icon with a red cross and that message means Windows lost the endpoint, not that the speakers died. The order of repairs matters.

TL;DR

Check **Device Manager** for a code 10 or a hidden device, restart the **Windows Audio** and **Audio Endpoint Builder** services, then reinstall the **chipset and audio driver**. A sleep-related driver crash causes most cases.

Before you start

Requirements

  • Admin rights
  • The audio driver package
  • Twenty minutes
Step by step

Instructions

01

Look at the device before the sound panel

The sound panel only lists endpoints that exist. Device Manager shows whether the controller is present, disabled or hiding under a warning sign.

devmgmt.msc > Sound, video and game controllers
02

Show hidden and disconnected devices

A device that failed to start after a sleep cycle often stays as a ghost entry. Removing the ghost forces a clean enumeration on the next scan.

View > Show hidden devices
tipRemove only the greyed-out audio entries. Deleting a working controller just adds a reboot.
03

Restart the two audio services

Windows Audio plays the sound, the Endpoint Builder creates the devices. If either is stopped, no endpoint exists no matter what the driver says.

net stop audiosrv & net stop audioendpointbuilder
04

Reinstall the driver from the vendor

A Windows Update driver for an older codec often fails after a feature update. Install the vendor package, reboot, and confirm the entry no longer shows a warning.

05

Check the firmware audio setting

Some boards disable the onboard codec when a front-panel header is unplugged, and laptops can disable it in the firmware when a dock is set as default. Look for an audio or HD Audio entry.

⚠ warningAfter a firmware update the audio controller can come back disabled. That looks exactly like a driver failure until you open the setup screen.
06

Repair the system files if it keeps returning

A missing or corrupted audio component survives every driver reinstall. A quick system file check repairs the component store without a reinstall.

sfc /scannow
Troubleshooting

Common issues

The device shows code 10

The driver cannot start. Remove the device with its driver, reboot and reinstall the vendor package.

It works until the machine sleeps

A power-management bug in the driver. Update it, or disable the selective suspend for the audio controller.

Only headphones work

The jack detection is stuck. Replug, or disable jack detection in the vendor control panel.

The services refuse to start

A dependency is stopped. Start the Windows Audio Endpoint Builder first, then Windows Audio.

FAQ

Frequently asked

Does a system restore help?

Only if the fault appeared after an update. Note the date first.

Can a BIOS reset fix it?

Yes when the codec was disabled in firmware. Loading defaults is quick to test.

How to undo this

Nothing here changes your data. If the vendor driver made it worse, roll it back in Device Manager under Properties > Driver > Roll Back Driver.
