电脑音响没声音怎么回事？音响没声音会让经常上网的人崩溃，作为上网必备的工具，音响没声音是一个十分令人头疼的问题。音箱突然没声音究竟是软件的问题还是硬件的问题？那么该怎么解决电脑音响没声音呢？接下来，小编就说说当遇到电脑音响没声音的情况该怎么办吧。
平常我们经常会遇到电脑不发声，音响没有声音。这种问题只能通过排查的方法来确定问题出在哪里。因此，要先查明原因，看是软件还是硬件出了故障，然后针对问题对症下药。那么电脑音响没声音怎么回事？该怎么解决？小编就针对电脑音响没声音做了如下操作步骤。
解决电脑音响没声音怎么回事图文操作
首先打开控制面板。
电脑(图1)
找到音频管理器(红色喇叭)。
电脑(图2)
找到“音频I/O”。
电脑(图3)
点击右上方“扳手”图标，就会出现如下图显示。
电脑(图4)
勾选“禁用前面板插口检测”并单击“OK”
电脑(图5)
硬件原因：（1）接触不良。音响使用时间过久造成内部电路老化，音响连接电脑时接触不良有可能会出现没有声音的现象。
解决方法：先检查音响连接是否正常，确保完好后还是没有声音可以安装驱动看看，如果驱动装好后还不见好，那说明音响坏了。

（2）音响线没连接好。
音响线没有插到对应的插孔，音响的音量置于最小的位置或音箱没有供电，都会出现电脑没声音了的情况。
解决方法：先将音响开关打开，音量调大，如果没有声音，就看下电脑主机的后面，后面的那个音频输出一般有三个口，分别为红、绿、蓝三色，红色是麦克，绿色是音响，蓝色是输出，音响线头也是有颜色的，对应插入相同颜色的插孔即可，插好后，再打开音响音量试试，看有没有声音。
电脑(图7)
有时会不小心将音量设定到静音或者音响音量旋钮调在最小音量上，都会出现没有声音的情况。点击系统右下角里的喇叭图标，先确认是否已开启音量，将声音调到适宜大小。如果右下角的“小喇叭”图标也不见了，就进入“控制面板”，双击“声音和音频设备”项，在弹出的“声音和音频设备属性”窗口中，选择“音量”页面，再把音量调节滑块调到合适的位置，并在“将音量调节图标放入任务栏”前打上钩，确定并退出

以上就是电脑音响没声音怎么回事的一些原因以及操作步骤了，希望这篇图文能够给一些网友带来一些解决该问题的帮助。
