I have been looking for means to control the volume from the application without success.
the registry has entries under Current_user\controlpanel\volume but these only serve for storing the last volume for the next use, not for real time changes.
I have found a small application that is an independent volume control, which shows that there is a way to do it. It is attached.

Anybody has an idea ?

I think that controlling the screen brightness in real time is a similar problem (without opening the windows form that has the sliding bar).
