某位版主提到可以删除MMCSS和Windows Audio之间的依赖关系，只是不知道怎么删除的。

这个要改注册表，以前安装win8时有爆音，曾经改过，不过那是先改注册表，再停止服务。

运行regedit打开注册表编辑器，定位以下键值：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Audiosrv

请默认值应该是下述情况：

你可以保存到记事本，然后另存为reg文件，再双击导入当前注册表。
同时，若后台有什么其他程序处于运行状态，建议先暂时关闭。

@woxihuan2011

注意不是我出的.笙儿版主的一篇文章中提到了禁止MMCSS服务优化网速,我当时就提醒她,Windows Audio依赖此服务,禁用它会导致系统无声.帖子好像在应用交流区,半夜发的.

woxihuan2011

在开始菜单运行里面输入services.msc打开服务窗口,检查一下有没有这个服务:Multimedia Class Scheduler
