'No Audio Output Device is Installed' Fix

The 'No Audio Output Device is Installed' fix encompasses various easily-usable and free solutions to malfunctioning sound devices. Errors with audio devices can be from corrupted or missing updates or other unexpected configuration issues with the system's audio hardware detection. Applying each 'No Audio Output Device is Installed' fix as appropriate, most users can resolve the problem and resume standard audio output quickly.

Solutions for Sound Going Missing

A dedicated sound card hasn't been the norm for years, and many users might take for granted where their sound comes from (usually, an integrated motherboard card). Still, keeping a finger on the pulse between audio output and hardware remains an integral part of being a responsible PC owner. A 'No Audio Output Device is Installed' fix can take several formats, most of which don't require modifying the internal hardware.

First, users should always check their audio devices. From the Device Manager, double-click the 'Sound, video and game controllers' listing to open it. Then, right-click each audio device and enable it (or disable and re-enable, if appropriate) manually. Note that rebooting may be necessary before Windows re-detects a newly-enabled device.

Users who've changed their motherboards (or sound cards, for much older systems) recently should double-check the hardware for issues. Audio output failure can be from cables failing or being loose. Always fully power off the PC, unplug it from any external power sources and take steps for reducing touch static before checking the internal hardware. However, hardware-based solutions usually should be left for specific, relevant situations or after testing every other option (see below for more software-based fixes).

Getting Sound Back by Updates

Driver software being out-of-date or corrupted also can be a cause of missing audio output. Users can right-click their audio devices in the Device Manager and use Windows's built-in driver-updating menu. While this feature is convenient, most users should avoid using third-party, even Microsoft-endorsed, updates, if practical. Users can guarantee that they have the latest and most appropriate update by checking their device's manufacturer, navigating to the company's website and downloading the newest driver update for their product personally.

In some cases, fully uninstalling the drivers may be a requirement before re-installing the old or new ones from scratch. Once again, users can do so from within the Device Manager. To install a new device, right-click the relevant entry (such as 'Sound, video and game controllers') and choose the Scan option for Windows to detect the hardware and find its driver automatically. Users also could choose the Action bottom on the top of the window and use 'Add legacy hardware.' The hardware wizard application will provide both manual and auto-detection choices for the installation.

As always, extreme hardware damage (such as from electrical surges) can require replacing the entire motherboard or other product but isn't a common source of audio output problems.

For most Windows users, a 'No Audio Output Device is Installed' fix is as simple as doing what they already should have done in the first place. Forgetting an update, shutting it down before it finishes, or plugging in a cable too carelessly are basic fumbles that can disrupt the user's audio experience (among others) but are never too late to fix.
