　　今天打开电脑，突然发现桌面右下角的任务栏上的小喇叭出现了红叉，当鼠标移到上面的时候显示“音频服务未启动”，这是怎么回事呢？一开始以为出现这个问题是声卡问题，但是检查了一下发现声卡没问题，经过查询后，总结出如下几种解决方法。

　　解决方法：

　　1、最简单做法：点小喇叭，把音量放到最大；

　　2、windows7音频服务无法启动可以打开控制面板的管理工具，打开服务列表，选择windows audio服务，右键属性，选择登录选项卡，修改登录选项为本地系统帐户，然后应用。然后再将登录选项修改为指定账户，浏览选择local service账户，然后确定应用重启以后即可恢复正常；

　　3、重新启动windows audio服务。步骤：》桌面计算机点右键》管理》服务和程序运用》服务》找到windows audio这个服务》点击右键》重启windows audio这个服务，问题就OK了；

　　4、windows7音频服务未启动或者可能是驱动问题，装一下驱动试试。

　　发现电脑任务栏上的喇叭图标出现红叉的时候，可以尝试用上面的几种方法来解决。如果无法解决的话，那可能是声卡驱动出现了问题，只不过显示正常而已，我们可以下载驱动精灵来安装最新的声卡驱动。
