Replacing Startup Sound I followed the hack for changing the startup sound to *none*, then decided that I would like to try using a different WAV file for the system startup. I copied the new WAV file to the Windows directory, and went in and pointed to the new file in the appropriate Registry Key, HKCU/Control Panel/Sounds/SystemStart. Upon power cycling the phone however, the new WAV file doesn't play. Is there some parameter that I'm missing? Do I have to rename the file to "piano.wav"?
