Windows 操作系统(Windows OS)不断更新新功能，而用户很少使用的一些现有功能要么完全删除，要么隐藏在操作系统深处。其中一项功能是立体声混音(Stereo Mix)。它是一种虚拟音频设备，可用于记录计算机扬声器当前播放的声音。该功能虽然很方便，但目前无法在所有Windows 10系统上找到。一些幸运的用户可以继续使用这个内置的录音工具，而另一些用户则需要为此下载专门的第三方应用程序。
我们在本文中解释了在Windows 10上启用(Windows 10)立体声混音(Stereo Mix)的两种不同方法，以及出现任何问题时的一些故障排除提示。此外，如果立体声(Stereo)混音功能不可用，还有几种替代方法可以记录计算机的音频输出。
如何在 Windows 10 上启用立体声混音？(How to Enable Stereo Mix on Windows 10?)
许多用户报告说，在更新到特定的Windows版本后，立体声混音功能突然从他们的计算机上消失了。(Stereo)一些人还误以为微软(Microsoft)将这项功能从他们手中夺走了，尽管Stereo mix 从未从Windows 10中完全删除，而是默认禁用。它也可能是您安装的众多第三方应用程序之一，这些应用程序自动禁用了立体声混音(Stereo Mix)设备。不过(Nevertheless)，请按照以下步骤启用立体声混音(Stereo Mix)。
1. 在任务栏上找到扬声器(Taskbar)图标（(Speaker icon)如果您没有看到扬声器图标，请先单击向上的“显示隐藏图标”箭头），右键单击(right-click )它，然后选择录音设备(Recording Devices)。如果缺少“录音(Recording)设备(Devices)”选项，请改为单击“声音” 。(Sounds )
2. 移至随后的声音(Sound)窗口的录音选项卡。(Recording )在这里，右键单击(right-click )Stereo Mix 并选择Enable。
3. 如果Stereo Mix录音设备未列出（显示），请右键单击(right-click)空白处并勾选Show Disabled Devices & Show Disconnected Devices选项。
4. 单击应用(Apply )保存新修改，然后单击确定(OK)关闭窗口。
您还可以从Windows 设置应用程序启用(Windows Settings)立体声混音(Stereo Mix)：
1. 使用Windows key + I的热键组合启动设置(Settings)并单击系统(System)。
2.从左侧面板切换到声音设置页面，然后单击右侧的(Sound )管理声音设备(Manage Sound Devices)。

如何使用立体声混音和故障排除技巧(How to Use Stereo Mix & Troubleshooting Tips)
使用立体声(Stereo)混音功能就像启用它一样简单。启动您喜欢的录音应用程序，选择立体声混音(Stereo Mix)作为输入设备而不是您的麦克风(Microphone)，然后点击录音按钮。如果您无法在应用程序中选择立体声混音(Stereo Mix)作为录音设备，请先拔下麦克风(Microphone)，然后按照以下步骤将立体声混音设置为计算机的默认设备 -(Stereo Mix)
1.再次打开声音窗口并移动到(Sound )录音(Recording )选项卡（参见(See)上一个方法的步骤 1。）
2. 首先，取消选择麦克风作为默认设备(deselect the Microphone as the default device)，然后右键单击立体声混音(right-click on Stereo Mix)并从随后的上下文菜单中选择设置为默认设备。(Set as Default Device)
这将在 Windows 10 上成功启用立体声混音。 (This will successfully enable the Stereo Mix on Windows 10. )如果您无法在录音应用程序中将立体声混音(Stereo Mix)视为设备，或者该功能似乎不像宣传的那样工作，请尝试以下故障排除方法。
方法 1：确保麦克风(Microphone)可用于访问(Access)
无法启用立体声混音(Stereo Mix)的原因之一是应用程序无法访问麦克风(Microphone)。出于隐私考虑，用户通常会禁止第三方应用程序访问麦克风(Microphone)，解决方案是简单地允许所有（或选定的）应用程序使用Windows设置中的(Windows Settings)麦克风(Microphone)。
1. 使用Windows key + I的热键组合启动Windows 设置(Settings )，然后单击隐私(Privacy )设置。
2.向下滚动(Scroll)左侧导航菜单，然后单击应用权限(App permissions.)下的麦克风。(Microphone )
3. 在右侧面板上，检查是否允许设备访问麦克风(check if the device is allowed to access the Microphone)。如果没有，请单击更改(Change )按钮并将以下开关切换为打开。

方法 2：更新或降级音频(Downgrade Audio)驱动程序
由于立体声混音(Stereo Mix)是特定于驱动程序的功能，因此您的计算机需要安装适当的音频驱动程序。它可以像更新到最新的驱动程序版本或恢复到支持立体声(Stereo)混音的先前版本一样简单。按照以下指南更新音频驱动程序。如果更新不能解决问题，请在Google上搜索您的声卡并检查它的哪个驱动程序版本支持立体声(Stereo)混音。
1. 按Windows Key+ R启动“运行”(Run)命令框，键入devmgmt.msc，然后单击“确定(OK)”打开设备管理器(Device Manager)应用程序。
2.单击左侧的小箭头，展开声音、视频和游戏控制器。(Sound, video and game controllers)
3. 现在，右键单击(right-click )您的声卡并从随后的菜单中选择更新驱动程序。(Update driver)
4. 在下一个屏幕上，选择自动搜索驱动程序(Search Automatically for drivers)。
立体声混音的替代品(Alternatives to Stereo Mix)
万维网上有许多第三方应用程序可用于记录计算机的音频输出。Audacity是最受欢迎的Windows记录器之一，下载量超过 1 亿次。缺乏立体声(Stereo)混音的现代系统包含WASAPI（Windows 音频会话 API(Windows Audio Session API)），它以数字方式捕获音频，因此无需将数据转换为模拟进行播放（用外行的话来说，录制的音频文件将具有更好的质量）。只需(Simply)下载Audacity，选择WASAPI作为音频主机，并将您的耳机或扬声器设置为环回设备。点击(Click)在录制(Record)按钮上开始。
很少有其他好的替代立体声(Stereo)混音是VoiceMeeter和Adobe Audition。录制计算机音频输出的另一种非常简单的方法是使用辅助电缆（两端都有 3.5 毫米插孔的电缆）。将一端插入麦克风(Microphone)端口（输出），另一端插入麦克风端口（输入）。现在您可以使用任何基本的录音应用程序来录制音频。

How to Enable Stereo Mix on Windows 10?
Windowѕ OS gets cоnstantly updated with new features while some of the existing ones that are seldom being uѕed by the users are either entirely removed or hidden deep іnside the OS. Оne such feature is the Stereo Mix. It is a virtual audio deνice that can be used to record the sound currently being played out of the computer speakers. The feature, although handy, cannot be foυnd on all Windows 10 systems nowadays. Some lucky usеrs can continue using this built-in recording tool, whіle others will need to download a specialized third-party aрplication for this рurpose.
We have explained two different ways to enable Stereo Mix on Windows 10 in this article along with some troubleshooting tips if any issues arise. Also, a couple of alternative ways to record the computer’s audio output if the Stereo mix feature is not available.
How to Enable Stereo Mix on Windows 10?
Many users reported that the Stereo mix feature suddenly disappeared from their computer after updating to a particular Windows version. A few were also under the misconception that Microsoft took the feature away from them, although Stereo mix was never entirely removed from Windows 10 but only disabled by default. It could also have been one of the many third-party applications you have installed that automatically disabled the Stereo Mix device. Nevertheless, follow the below steps to enable Stereo Mix.
1. Locate the Speaker icon on your Taskbar (if you do not see the speaker icon, first click on the upward-facing ‘Show hidden icons’ arrow), right-click on it, and select Recording Devices. If the Recording Devices option is missing, click on Sounds instead.
2. Move to the Recording tab of the ensuing Sound window. Here, right-click on Stereo Mix and select Enable.
3. If the Stereo Mix recording device isn’t listed (being displayed), right-click on the blank space and tick Show Disabled Devices & Show Disconnected Devices options.
4. Click on Apply to save the new modifications and then close the window by clicking on OK.
You can also enable Stereo Mix from the Windows Settings application:
1. Use the hotkey combination of Windows key + I to launch Settings and click on System.
2. Switch to the Sound settings page from the left-hand panel and click on Manage Sound Devices on the right.
3. Under the Input devices label, you will see Stereo Mix as Disabled. Click on the Enable button.
That’s it, you can now use the feature to record your computer’s audio output.

How to Use Stereo Mix & Troubleshooting Tips
Using the Stereo mix feature is as easy as enabling it. Launch your preferred recording application, select Stereo Mix as the input device instead of your Microphone, and hit the record button. If you are unable to select Stereo Mix as the recording device in the application, first unplug your Microphone and then make Stereo Mix the default device for your computer by following the below steps-
1. Open the Sound window once again and move to the Recording tab (See step 1 of the previous method.)
2. First, deselect the Microphone as the default device, and then right-click on Stereo Mix and select Set as Default Device from the ensuing context menu.
This will successfully enable the Stereo Mix on Windows 10. In case you are unable to view Stereo Mix as a device in your recording application or the feature doesn’t seem to work as advertised, try the below troubleshooting methods.
Method 1: Ensure Microphone is available for Access
One of the reasons why you may fail to enable Stereo Mix is if applications do not have access to the Microphone. Users often disable third-party applications from accessing the Microphone for privacy concerns and the solution is to simply allow all (or selected) applications to use the Microphone from the Windows Settings.
1. Use the hotkey combination of Windows key + I to launch Windows Settings then click on Privacy settings.
2. Scroll down the left navigation menu and click on Microphone under App permissions.
3. On the right panel, check if the device is allowed to access the Microphone. If not, click on the Change button and toggle the following switch to on.

Method 2: Update or Downgrade Audio drivers
Since Stereo Mix is a driver-specific feature, your computer needs to have the appropriate audio drivers installed. It could be as easy as updating to the latest driver version or reverting back to a previous version that supported the Stereo mix. Follow the below guide to update audio drivers. If updating doesn’t resolve the issue, perform a Google search for your sound card and check which driver version of it supports Stereo mix.
1. Press Windows Key+ R to launch the Run command box, type devmgmt.msc, and click on OK to open the Device Manager application.
2. Expand Sound, video and game controllers by clicking on the tiny arrow to its left.
3. Now, right-click on your sound card and select Update driver from the ensuing menu.
4. On the next screen, select Search Automatically for drivers.
Alternatives to Stereo Mix
There are a number of third-party applications available on the world wide web that can be used to record the computer’s audio output. Audacity is one of the most popular recorders for Windows with over 100M downloads. Modern systems that lack Stereo mix contain WASAPI (Windows Audio Session API) instead which captures audio digitally and thus, eliminates the need of converting the data to analog for playback (In layman’s terms, the recorded audio file will be of better quality). Simply download Audacity, choose WASAPI as the audio host, and set your headphones or speakers as the loopback device. Click on the Record button to start.
Few other good alternatives to Stereo mix are VoiceMeeter and Adobe Audition. Another very easy way to record the computer’s audio output is to use an aux cable (a cable with 3.5 mm jack on both ends.) Plug one end into the Microphone port (output) and the other into the mic port (input). Now you can use any basic recording application to record the audio.
