问题补充

怎么办啊

今天碰到一台机器，在设备管理器里没有叹号，声卡也已安装官方驱动，但是在声音和音频设备中还是显示灰色，机器也没有声音。找来找去原来是windows audio服务丢失了。（判断是否为windows audio服务引起上述声卡不能用问题的方法是在控制面板－管理工具－服务中查找是否有windows audio服务并查看是否已自动启动？）

解决方法如下：

1、将下面的文件复制到文本文件中，保存后改名为Audio.reg

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"="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\\LEGACY_AUDIOSRV\\0000"

"Count"=dword:00000001

"NextInstance"=dword:00000001

2、双击刚刚创建并保存的audio.reg文件，并重启机器就OK了。
