Win7系统声音方案无法更改？

1、在Win7桌面开始菜单中，打开运行对话框，然后在运行窗口中输入regedit命令并按下确定按钮即可打开注册表编辑器。

2、接着在Win7系统注册表中，将其路径定位至HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run，接着在Run项的右侧窗格中，新建“字符串值”，命名为Systray。然后双击打开Systray键值，再将其编辑为c:windowssystem32Systray.exe。

1.设定更改对声音马上生效,不需重启电脑.

2.每个设定经本人试听后证实都对声音有影响.

3.修改后,你的背景程式反应时间,一些程式或游戏性能等可能会有轻微下降.

4.严格按照上面数字设定,注意数字单位(十进制和十六进制).

你用其他数字声音只会变差,,除了"Clock

Rate"这一项

6.修改完後,声音的hifi性会有比较明显的提升,音场空灵感增强,清晰度通透度增强,声音稳定性改善(声音紧张度下降)
