有一些读者抱怨他们的 Windows 11/10 计算机中的音频驱动程序有问题。问题是，在他们重新启动计算机后，他们发现音频输入^{(Audio Input)}和输出^(Output)设备已被卸载，他们必须重新安装它们才能让它们再次工作。这篇文章将检查多种原因和解决方案，以帮助您解决重新启动时卸载音频输入和输出设备的问题。

最常见的原因之一是任何最近的Windows 更新^{(Windows Update)}都可能导致该问题。结果是不稳定的驱动程序无法识别连接的设备。还有其他原因，例如设备断开连接。

^{(Audio Input)}重新启动时卸载音频输入和输出设备^(Output)

请按照以下步骤解决音频^(Audio)输入和输出设备的问题。

1. 运行内置音频疑难解答^{(Built-In Audio Troubleshooter)}
2. 损坏的音频驱动程序
3. 重新启用您的音频设备
4. 未安装音频输出设备^{(Audio Output Device)}。
5. ^(Download)从制造商网站^(Website)下载和更新驱动程序

您必须知道计算机上的输入和音频设备列表。

1]运行^(Run)内置音频疑难解答^{(Built-In Audio Troubleshooter)}

Windows内置的疑难解答程序可以修复大多数问题，最好在进行任何高级疑难解答之前运行它。

打开Windows 11设置，然后导航到System > Troubleshoot > Additional疑难解答 > 播放音频^(Audio)。选择它，然后运行音频疑难解答^{(run the audio troubleshooter)}。

转到Windows 10设置，然后导航到更新^(Update)和安全> Troubleshoot > Additional疑难解答 > 播放音频^(Audio)。

运行疑难解答程序，让向导完成其工作——诸如禁用音频设备、任何软件阻塞、重新启动服务等问题。

阅读^(Read)：没有音频或声音丢失^{(No Audio or Sound is missing)}。

2]重新启用您的音频设备

如果即使设备已打开也找不到该设备，则它可能已被禁用。

• ^{(Type Control)}在开始菜单中^(Start)键入 Control，然后打开经典的控制面板^{(Control Panel)}。
• 单击声音图标。
• 右键单击^{(Right-click)}窗口上的任意位置，然后选择显示禁用的设备^{(Show Disabled Devices)}
• 该列表将刷新，如果之前未列出该设备，您应该能够看到它。
• 右键单击它，然后选择启用

您可以为Playback和Recording重复它。

读取^(Read)： 未检测到 HDMI 音频设备。^{(HDMI Audio device not detected.)}

3]没有连接音频输出设备^{(No Audio Output Device)}

可能没有连接音频输出设备^{(no audio output device is connected)}。例如，您可能使用 3.5 毫米音频插孔或蓝牙^(Bluetooth)连接了一个较早的扬声器，但它尚未通电。在这种情况下，Windows通常应该说它无法找到该设备。如果您打开设备电源，然后使用系统托盘上的声音图标，您可以切换到它。

提示^(TIP)：如果没有找到音频输入设备，这篇文章将为您提供帮助。^{(no audio input device is found.)}

4]损坏的音频驱动程序

系统文件和驱动器有时会损坏。唯一的出路是使用设备管理器卸载设备，然后使用扫描功能重新安装。此方法将确保解决问题。

• Use WIN + X，然后按 M 打开设备管理器
• 找到音频设备，然后右键单击它，然后选择卸载它。
• 右键单击^{(Right-click)}顶部的计算机名称，然后选择扫描硬件^(Scan)更改^(Hardware)。

它将自动找到设备并安装所需的驱动程序。您还可以选择从 OEM 网站安装最新的驱动程序。

阅读^(Read)： 一项或多项音频服务未运行。^{(One or more audio service isn’t running.)}

5 ] 从制造商的网站下载^{(] Download)}和更新驱动程序

如果问题发生在最近的Windows 更新^{(Windows Update)}之后，您可能需要更新设备的驱动程序。如果没有更新，但制造商网站^(Website)上可能会提供最近的更新。虽然 Windows 应该能够找到并安装它，但如果没有，您可以手动下载并更新驱动程序。^{(manually download and update the driver.)}

如果没有任何效果并且您迫切希望让音频设备正常工作，那么您唯一能做的就是回滚最近的Windows更新并查看它是否有效。

Audio Input and Output device uninstalled upon restart in Windows 11/10

Τhere are several complaints from readers who’ve been exрeriencing рroblems with the audio drivers in their Windows 11/10 сomputers. The problem is that, aftеr they restart their computers, they find that the Audio Input and Output devices have beеn uninstalled, and they have to reinstall them to get them working again. This post will examine multiplе reasоns and solutiоns that will help you resolve thе problem where the audio input and output device uninstalled upon restart.

One of the most common reasons is any recent Windows Update could have caused the problem. The result is an unstable driver that fails to recognize the connected device. There are other reasons as well, such as disconnected devices.

Audio Input and Output device uninstalled upon restart

Follow these steps to resolve the problem with your Audio input and output devices.

1. Run the Built-In Audio Troubleshooter
2. Corrupted Audio Drivers
3. Re-Enable Your Audio Device
4. No Audio Output Device is installed.
5. Download & update driver from the Manufacturer’s Website

You must know the list of input and audio devices on the computer.

1] Run the Built-In Audio Troubleshooter

Windows built-in troubleshooter can fix most things, and it is always best to run it before any advanced troubleshooting.

Open Windows 11 Settings, and navigate to System > Troubleshoot > Additional troubleshooters > Playing Audio. Select it, and run the audio troubleshooter.

Go to Windows 10 Settings, and navigate to Update and security > Troubleshoot > Additional troubleshooters > Playing Audio.

Run the troubleshooter, and let the wizard do its job—problems such as disabled audio devices, any software block, restarting of services, and so on.

2] Re-Enable Your Audio Device

If you cannot find the device even though it is turned on, it may have been disabled.

• Type Control in the Start menu, and open the classic Control Panel.
• Click on the Sound icon.
• Right-click anywhere on the window, and select Show Disabled Devices
• The list will refresh, and if the device was not listed earlier, you should be able to see it.
• Right-click on it, and choose to enable

You can repeat it for both Playback and Recording.

3] No Audio Output Device is connected

It is possible that no audio output device is connected. For example, you may have an earlier connected speaker using the 3.5 mm audio jack or Bluetooth, but it has not been powered up. In that case, Windows should typically say that it is not able to find the device. If you power on the device and then use the sound icon on the system tray, you can switch to it.

TIP: This post will help you if no audio input device is found.

4]  Corrupted Audio Drivers

System files and drives get corrupted sometimes. The only way out is to uninstall the device using the device manager and then reinstall using the scanning feature. This method will make sure to fix the problem.

• Use WIN + X, followed by M to open the device manager
• Locate the audio device, and right-click on it, and choose to uninstall it.
• Right-click on the computer name on the top, and select Scan for Hardware changes.

It will automatically find the device and install the required driver. You can also choose to install the latest drivers from the OEM’s website.

Read: One or more audio service isn’t running.

5] Download & update the driver from the manufacturer’s website

If the problem occurred after a recent Windows Update, you might have to update the devices’ driver. If there was no update, but a recent update may be available on the Manufacturer’s Website. While Windows should be able to find and install it, but if it doesn’t, you can manually download and update the driver.

If nothing works out and you are desperate to get the audio device working,  the only thing you can do is roll back the recent Windows update and see if that works.
