您是否在Windows 10(Windows 10)的系统托盘上看到带有红色 x 形符号的音量图标？如果将光标放在它上面，您还应该看到“未安装音频输出设备(No Audio Output Device)”错误通知。
当您的计算机由于损坏、过时或不兼容的音频驱动程序而无法检测到音频设备时，通常会发生这种情况。更糟糕的是，在您解决问题之前，您将听不到任何声音。
如果重新启动计算机没有任何作用，那么下面的故障排除提示应该可以帮助您修复Windows 10中的“未安装音频输出设备(No Audio Output Device)” 。
运行音频疑难解答
Windows 10 带有内置的音频疑难解答程序，可以自动检测和修复计算机上与音频相关的问题(fix audio-related issues on your computer)。最好先运行它，然后再深入研究其余的修复程序。
1. 打开开始(Start )菜单并选择设置(Settings)。
2. 选择更新和安全(Update & Security)。
3. 切换到故障排除(Troubleshoot )侧选项卡。
4. 选择其他疑难解答(Additional troubleshooters)。
5. 选择播放音频(Playing Audio)。然后，选择运行疑难解答(Run the troubleshooter)按钮。
按照屏幕上的说明解决计算机上音频设备的问题。如果疑难解答程序要求您在多个音频设备之间进行选择，请为每个设备重复运行它。
断开(Disconnect)并重新连接外部音频输出设备(Reconnect External Audio Output Device)
您是否将外部音频输出设备（例如耳机）物理连接到您的计算机？尝试删除它。然后，重新启动计算机并重新连接。如果这没有帮助，请继续进行其余的修复。
卸载并重新安装音频设备(Reinstall Audio Device)
在计算机上卸载并重新安装音频设备/声卡是一种有效的修复方法，可以帮助解决“未安装音频输出设备”错误。Windows 10中的设备管理器(Device Manager)小程序应该可以帮助您。

7. 再次选择下一步(Next )以安装音频设备。
8. 选择完成(Finish )以完成安装过程。
9. 重新启动您的计算机。
(Did)那有帮助吗？如果没有，让我们看看接下来你能做什么。
重置 Windows 10
如果上述修复均无济于事，请尝试将 Windows 10 重置为其出厂默认设置(resetting Windows 10 to its factory defaults)。您可能正在处理与音频相关的深层问题，只有一组新的Windows设置才能解决该问题。您可以选择保持数据完整，但最好在继续之前创建计算机的备份。(create a backup of the computer)
1. 打开开始(Start )菜单并选择设置(Settings)。
2. 选择更新和安全(Update & Security)。
3. 切换到恢复(Recovery )选项卡。在重置(Reset)此 PC 部分下，选择开始(Get started)按钮以启动重置过程。
如果重置Windows 10不能帮助修复“未安装音频输出设备”错误，您可能正在查看特定于设备的问题。联系音频设备制造商寻求更多帮助。
How to Fix “No Audio Output Device Is Installed” in Windows 10
Do you see a volume іcon with a red x-shaped symbol on the system tray in Windows 10? If you place your cursor over it, you should alѕo seе a “No Audio Output Device iѕ installed” error notіfication.
That typically happens when your computer fails to detect an audio device due to corrupt, outdated, or incompatible audio drivers. To make things worse, you will experience no sound at all until you resolve the issue.
If restarting your computer doesn’t do anything, then the troubleshooting tips that follow should help you fix “No Audio Output Device is installed” in Windows 10.
Run Audio Troubleshooter
Windows 10 comes with a built-in audio troubleshooter that can automatically detect and fix audio-related issues on your computer. It’s best to run that first before you dive into the rest of the fixes.
1. Open the Start menu and select Settings.
2. Select Update & Security.
3. Switch to the Troubleshoot side-tab.
4. Select Additional troubleshooters.
5. Select Playing Audio. Then, select the Run the troubleshooter button.
Follow the onscreen instructions to fix problems with the audio device on your computer. If the troubleshooter asks you to pick between multiple audio devices, run it repeatedly for each one of them.
Disconnect and Reconnect External Audio Output Device
Do you have an external audio output device (such as a headphone) connected to your computer physically? Try removing it. Then, restart your computer and reconnect it. If that did not help, continue on with the rest of the fixes.
Uninstall and Reinstall Audio Device
Uninstalling and reinstalling the audio device/sound card on your computer is a potent fix that can help resolve the “No Audio Output Device is installed” error. The Device Manager applet in Windows 10 should help you with that.
1. Right-click the Start button and select Device Manager.
2. Expand the Sound, video and game controllers section.
3. Right-click your computer’s audio device and select Uninstall Device.
4. Check the box next to Delete the driver software for this device (if available) and select OK to uninstall the device.
5. Expand the Audio inputs and outputs section and repeat steps 3–4.
6. Restart your computer. That should prompt your computer to reinstall the audio device.
7. Re-open the Device Manager. You should see the reinstalled audio device listed underneath the Sound, video and game controllers and Audio inputs and outputs sections. If not, right-click a vacant area and select Scan for hardware changes.
If reinstalling the audio device fixed the issue, you should see a fully functional volume icon on the system tray.
Update Audio Drivers
Try updating the audio drivers on your computer. Head over to the device manufacturer’s website, specify the correct make and model of the sound card, and download the latest drivers. Then, either install them yourself or have Windows 10 do that for you via the Device Manager. If you prefer the second method, go through the following steps.
1. Right-click the Start menu and select Device Manager.
2. Expand the Sound, video and game controllers section.
3. Right-click the audio driver and select Update driver.
4. Select Browse my computer for drivers.
5. Use the Browse button to locate the folder containing the downloaded drivers.
6. Select Next and follow the remaining prompts to install the new audio drivers.
Alternatively, you can use a driver updater utility to download and install the correct audio drivers for your computer automatically.
Update Windows 10
Sometimes, updating Windows 10 can break the audio device drivers on your computer. The best way to resolve that is to install any subsequent incremental updates.
Back in 2018, for example, the “No Audio Output Device is installed” error showed up on computers with Intel-based audio chipsets due to a faulty driver pushed out by Windows Update. Microsoft quickly fixed that with another minor update.
1. Open the Start menu and select Settings.
2. Select Update & Security.
3. Select Check for updates.
4. Select Download & install to update Windows 10.
5. Select View optional updates (if visible on the same screen). Then, check the boxes next to any audio device-related updates and select Download and install.
Install Audio Device as Legacy Hardware
If you don’t see your audio device driver listed within the Device Manager, you can try setting it up as a legacy device. You can also do that if the “No Audio Output Device is installed” error still keeps showing up despite going through the fixes above.
1. Right-click the Start button and select Device Manager.
2. Select any item within the Device Manager. Then, open the Action menu and select Add legacy hardware.
3. Select Next on the Welcome to the Add Hardware Wizard screen.
4. Pick the Install the hardware that I manually select from a list (Advanced) option and select Next.
5. Pick Sound, video and game controllers as the hardware type and select Next.
6. Select the audio manufacturer from the list to the left of the screen. Then, select the model from the right side. If you have a disk that contains the drivers for the audio device, select Have Disk and specify the disk’s location. Select Next to continue.
7. Select Next again to install the audio device.
8. Select Finish to complete the installation process.
9. Restart your computer.
Did that help? If not, let’s check out what you can do next.
Reset Windows 10
If none of the fixes above helped, try resetting Windows 10 to its factory defaults. You may be dealing with a deep underlying audio-related issue that nothing but a fresh set of Windows settings can fix. You can choose to keep your data intact, but it’s best to create a backup of the computer before you go ahead.
1. Open the Start menu and select Settings.
2. Select Update & Security.
3. Switch to the Recovery tab. Under the Reset this PC section, select the Get started button to initiate the reset procedure.
If resetting Windows 10 did not help fix the “No Audio Output Device is installed” error, you’re likely looking at a device-specific issue. Reach out to the audio device manufacturer for additional help.
