Disable shutter sound

From TreoCentral

To disable the shutter sound on the Treo 700wx's camera use a registry editor and go to:

HKLM\System\Pictures\Camera\OEM\SoundFile

Under "String" it should say

\Windows\ShutterSound312.wav

Simply edit out this line and leave the string empty.

Exit the registry and do not soft reset for at least a couple of minutes to let the change write to ROM.

No soft reset is needed for change to occur.

Now, whenever you take a picture there will be no sound.
