如何修复Windows 10中的声音问题
You launch a PC game or stream a movie, but you don’t hear any sound. On the surface, there’s no apparent reason for the lack of audio. This guide shows you how to fix sound problems in Windows 10.
您启动了PC游戏或播放电影，但没有听到任何声音。 从表面上看，没有明显的原因缺少音频。 本指南说明如何解决Windows 10中的声音问题。
Unfortunately, sound issues can be tricky. Problems could merely reside in third-party software, requiring a patch. Issues could also stem from within Windows 10 itself or the underlying hardware. Possible fixes include installing new drivers, tweaking settings, or even revert to a previous restore point.
不幸的是，声音问题可能很棘手。 问题可能仅存在于第三方软件中，需要修补程序。 问题也可能源于Windows 10本身或底层硬件。 可能的修复包括安装新的驱动程序，调整设置，甚至恢复到先前的还原点。
This guide begins with the easy steps and moves deeper into Windows 10 if you continue to face audio issues.
本指南从简单的步骤开始，如果您继续遇到音频问题，则可以更深入地进入Windows 10。
首先检查简单修复 (Check for Simple Fixes First)
There’s nothing more embarrassing than yelling at the PC over sound issues stemming from an unintentional press of the microphone’s mute button.
没有比在PC上大喊大叫的尴尬了，这是由于无意中按下了麦克风的静音按钮而引起的声音问题。
First, verify that the sound isn’t muted on the PC end. If your keyboard has volume controls, press a key or turn a slider to see if the on-screen volume bar raises and lowers. You can also bring up the taskbar to examine the “speaker” icon parked next to the system clock.
首先，确认PC端的声音没有被静音。 如果您的键盘具有音量控制，请按一个键或转动一个滑块以查看屏幕上的音量栏是否在升高和降低。 您也可以调出任务栏以检查停在系统时钟旁边的“扬声器”图标。
As shown below, an “X” next to the virtual speaker icon means your audio is muted. Simply click the speaker button to expand the volume panel.
如下所示，虚拟扬声器图标旁边的“ X”表示您的音频已静音。 只需单击扬声器按钮即可展开音量面板。
Next, click the speaker icon to the left of the slider to unmute.
接下来，单击滑块左侧的扬声器图标以取消静音。
You should also verify that the sound isn’t muted or turned down on the hardware end. For instance, your speakers may have volume buttons, or they may be accidentally unplugged from the PC or power outlet.
您还应该在硬件端确认声音没有被静音或调低。 例如，您的扬声器可能具有音量按钮，或者可能不小心将其从PC或电源插座中拔出。
Likewise, your headset or microphone may include in-line volume dials that are turned down, or they may just be unplugged from the PC.
同样，您的头戴式受话器或麦克风可能包括已调低的嵌入式音量拨盘，或者可能刚刚从PC拔下了插头。
The example below shows a Logitech headset’s in-line controls for sound (dial) and a built-in microphone (toggle).
下面的示例显示了Logitech耳机的声音(拨号)和内置麦克风(切换)的嵌入式控件。
Another simple fix is to verify that the problem isn’t related to a specific app or program installed on your computer. There may be something wrong with the app or program itself that needs patching or audio is turned down or muted from within.
另一个简单的解决方法是验证问题是否与计算机上安装的特定应用程序或程序无关。 应用或程序本身可能存在问题，需要修补或音频被关闭或从内部静音。
This example shows muted audio on YouTube.
此示例显示了YouTube上的静音音频。
Other fixes you can try include installing all Windows 10 updates or restarting your PC.
您可以尝试进行的其他修复包括安装所有Windows 10更新或重新启动PC 。
验证默认音频设备 (Verify the Default Audio Device)
Generally, you should only have one installed audio device. However, the list stacks up once you begin piling on external devices like the HTC Vive, a wireless Xbox controller, a headset, and so on.
通常，您应该只安装一个音频设备。 但是，一旦您开始堆积在HTC Vive，无线Xbox控制器，头戴式耳机等外部设备上，该列表就会堆积起来。
There may be situations where you switch from a headset to a laptop’s built-in speakers, but Windows 10 still outputs audio through your disconnected headset.
在某些情况下，您可能从头戴式耳机切换到笔记本电脑的内置扬声器，但Windows 10仍会通过断开连接的头戴式耳机输出音频。
You can verify the default audio device in one of two ways: from the taskbar or through the Control Panel.
您可以通过以下两种方式之一来验证默认音频设备：从任务栏或通过控制面板。
任务栏路线 (The Taskbar Route)
Click on the “speaker” icon next to the system clock. You’ll see a name listed above the volume pop-up panel. Click the name to reveal a pop-up list labeled “Select Playback Device” and choose a different audio device until you hear a sound.
单击系统时钟旁边的“扬声器”图标。 您会在音量弹出面板上方看到一个名称。 单击名称以显示一个标记为“选择播放设备”的弹出列表，然后选择其他音频设备，直到听到声音为止。
If none of those work, move on to the “Run the Troubleshooter” step.
