Windows Mobile Smartphone Sound Settings

Many settings on a smartphone can be changed from the registry. PHM has a free registry editor for the smartphone. The settings are often easier to understand in hexadecimal format where number values go from 0-9 and then A-F. The PHM registry editor allows you to see numbers as either binary, hexadecimal or decimal. Decimal values can be converted using the Windows calculator in scientific mode. Entering a number in the calculator then clicking the radio button labeled "Hex" will convert the value.

Changes to the registry will go into effect after restarting the phone.

• HKEY_CURRENT_USER\ControlPanel\SoundCategories - Various phone sounds including the ring, alarm and system volume. These also found in the Settings. The values go from 0-9. Setting HKEY_CURRENT_USER\ControlPanel\SoundCategories\InCall\InitVol to zero disables the sound when initiating a call.
• HKEY_CURRENT_USER\ControlPanel\Volume\Volume - Controls the earpiece volume. Its values go from 0-4293967295, in hexadecimal the upper limit is an 8 integer value: FFFFFFFF.
• HKEY_CURRENT_USER\ControlPanel\Phone\Vol - Controls volume during a call. Its values go from 0-65535, in hexadecimal the upper limit is an 4 integer value: FFFF.
