应该还是设置的问题吧……不懂，坐等高手

可能是系统混音器的问题，说白了就是驱动安装不正确或者缺失
楼主可以试试重装下声卡驱动
或者看看设备管理器里“声音、视频和游戏控制器”那里有没有问题
第一感觉是这样的，情况复杂，楼主自己判断吧

   设备管理器也看了，看着没什么问题，真郁闷了，前一阵子倒真是还原过系统

开关打开了木有

   这么白痴的错误一般不会犯的~

楼主是什么系统，WINXP还是WIN7，如果是WIN7的话这种现象很常见，就是声卡驱动问题，装驱动就可以了
WINXP就没有那么复杂，一般驱动都集成有，如果你的声卡不常见，也得自己找驱动

   xp的系统，前一阵子还原了，不过驱动应该没问题
