没有活动的混音器设备可用，怎么办啊？

以下方法是我在网上找的，但前几天我的机子也出现同样的问题，用了他的方法，管用方法一网搜了下，论坛上的回答几乎一致：卸载声卡驱动重装，问题依旧！后来想到是否安装某些软件出现了问题，来到“删除添加程序”，发现“迅雷”的图标异常，卸载重启之后，双击“音量”一切恢复正常。方法二 运行命令：Services.msc ，启动Windows Audio 服务，然后马上就可以用了。当然，也可以右击我的电脑---管理---服务--开启Windows Audio 服务如果找不到Windows Audio 服务把下列文件用audio.reg命名,导入注册表.Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioSrv]"DependOnService"=hex(7):50,00,6c,00,75,00,67,00,50,00,6c,00,61,00,79,00,00,00,\52,00,70,00,63,00,53,00,73,00,00,00,00,00"Description"="管理基于 Windows 的程序的音频设备。如果此服务被终止，音频让洞设备及其音效将不能正常工作。如果此服务被禁用，任何依赖它的服务将无法启动。""DisplayName"="Windows Audio""ErrorControl"=dword:00000001"Group"="坦缺枯AudioGroup""ImagePath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,\74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,\00,76,00,63,00,68,00,6f,00,73,00,74,00,2e,00,65,00,78,00,65,00,20,00,2d,00,\6b,00,20,00,6e,00,65,00,74,00,73,00,76,00,63,00,73,00,00,00"ObjectName"="LocalSystem""Start"=dword:00000002"Type"=dword:00000020[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioSrv\Parameters]"ServiceDll"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,\00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,\61,00,75,00,64,00,69,00,6f,00,73,00,72,00,76,00,2e,00,64,00,6c,00,6c,00,00,\00"ServiceDllUnloadOnStop"=dword:00000001[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioSrv\Enum]"0"="Root\\扮茄LEGACY_AUDIOSRV\\0000""Count"=dword:00000001"NextInstance"=dword:00000001
