wm6.1 改ringtone聲量

google搵到以下registry

Increase Ring and InCall Volume
HKEY current user/ControlPanel/SoundCategories/InCall/InitVol (dword)
- value Data is 5
HKEY current user/ControlPanel/SoundCategories/Ring/InitVol (dword)
- value Data is 5
HKEY current user/ControlPanel/SoundCategories/System/InitVol (dword)
- value Data is 5
HKEY current user/ControlPanel/Volume/Volume (dword)
- Value data is 4294967295


係咪改HKEY current user/ControlPanel/SoundCategories/Ring/InitVol 就可以改喇叭大細聲?
最多改到5?但好似改做1或5都無乜分別
個數字可唔可以再改大d?最大幾多?
請高人指點
