I recently moved from Ubuntu to Windows 7 on my home PC. It has generally been a quite pleasant experience, but of course some things are not perfect. Among them is this issue:

When for exampe my son is playing a game in his browser and I use fast user switching to get to my account, his sound is still playing. This is of course very annoying if I want to play some sound of my own.

My options seem to be:

• Mute all sound (for all users)
• Kill his (and all other users') applications that output sound

I would like this behaviour:

• When I log in, all sound from other users is automatically muted

Is this possible? It sounds like the obvious behaviour, but some googling leads me to believe this is how Windows behaves.
