I made a phone call. I captured the registry settings with the in call volume set to the 5th notch and then changed the volume to the 2nd notch and captured it again. Here are the differences in the registry:
5th notch in call volume:
Code:
REGEDIT4
[HKEY_CURRENT_USER\ControlPanel\PhoneVolume]
"DownlinkPhoneVolume"=dword:000000FF
"MappedDownVolume"=dword:000000FA
[HKEY_CURRENT_USER\ControlPanel\Phone]
"Vol"=dword:0000FFFF
2nd Notch In call volume:
Code:
REGEDIT4
[HKEY_CURRENT_USER\ControlPanel\PhoneVolume]
"DownlinkPhoneVolume"=dword:00000033
"MappedDownVolume"=dword:00000032
[HKEY_CURRENT_USER\ControlPanel\Phone]
"Vol"=dword:00003333
Try #2....
And just to be sure, here are the settings for the 4th notch:
Code:
REGEDIT4
[HKEY_CURRENT_USER\ControlPanel\PhoneVolume]
"DownlinkPhoneVolume"=dword:000000CC
"MappedDownVolume"=dword:000000C8
[HKEY_CURRENT_USER\ControlPanel\Phone]
"Vol"=dword:0000CCCC
