Taken from the API docs: "Using Sound Preferences on All Palm OS Devices
Because the user chooses sound preference settings, your application should respect them and adhere to their values. Further, you should always treat sound preferences as read-only values. " Also in the docs: "The PrefSetPreference function writes to stored preference values without affecting cached values. New values are read at the next system reset. The system-use-only SndSetDefaultVolume function updates cached values but not stored preferences. Applications should avoid modifying stored preferences or cached values in favor of respecting the user's choices for preferences. " I don't know if this has changed, it could be why its not working. http://oasis.palm.com/dev/kb/manuals/1780.cfm may help. ----- Original Message ----- From: "Barry Peet" <[EMAIL PROTECTED]> Newsgroups: palm-dev-forum To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Wednesday, September 11, 2002 11:09 AM Subject: Set system sound > Ok, i have a question that must be answered before somewere, but i cant find > where... > > I'm trying to control the system sound volume from my application, using > > PrefSetPreference(prefSysSoundVolume, 0); > > (i.e. turn the system sound off) seems to have no effect.
