My usecase is as this.
The PC is shared and there are two users logged in at the same time. The first user puts internet radio on speaker, has got browser running with some rogue tab opened that plays a sound from time to time.
The second user switches to his user session leaving the other running with the audio. All is well until Skype call comes in, or the user decides to play a youtube clip. There seem to be no way to control the audio of the applications on the other session (or even entire session) from the built-in mixer.
The harsh method is to kill the winamp/browser on the other session.
Perhaps there is a simple way to do that.
Note: I tried running volume.exe with admin rights - does not help.
