I am running Windows 2000 and have set up Outlook to play a .wav file when email comes in. It's very useful for alerting me to new mail when I'm in another room in the house, but at night I have to remember to turn down the speaker volume or I'm awakened in the middle of the night by my PC announcing that new mail has arrived. Windows has a software volume controller in the Applications program group, so does anyone know of a way to schedule the muting of sounds. It would be great to set up my system to automatically mute itself at 9pm and return the volume to it's preset in the morning, at around 7am. Perhaps there is even a bored software engineer out there who might like to take up the challenge and produce a little freeware utility that does what I'd like ?? Thanks Andrew Foster
