But cannot get this to work in Vista.

May I know what is missing?Can anyone help me...

Thanks in advance

Check Device Manager, any yellow ? or ! marks showing, report shows C-Media as sound adapter, check this to see if default driver

Go to Control Panel / Sound & Audio Devices / Properties / Sound Playback – click on down arrow and check that the correct audio is selected. Typically the problem will be something “modem line 0 playback” has been substituted for the correct audio device.

Hope this helps

This has always been an issue, and I think the fact that it works on XP is more luck than anything else.

Under Windows, only the active session which owns the desktop is allowed to play sound. Services exist in a separate session and do not have access to the desktop by default. The easiest solution is usually to have a client component that runs under the user session and communicates to your service. This client application need not be visible or even own a window. You can set the application to start automatically with the user logon. I don't think there is a way to play sounds anymore without a user logged on. I'm not

1st, user need this application running without logon to Windows.

2nd, this application will continuously monitor event and boardcast via speaker (something like what you heard in Airport terminal).
