It's a bit of a complicated question, but I run Input Director together with SoundIt to also share sound over network.
When I run games on both client and master and have the "activate windows on hover" function in windows 10 enabled, the game windows on my client go back to background when I move back to my main system (which is exactly what I want, so no multiple sound sources.)
But the same does not happen when I go from my main to my client pc. The sound of the main PC's game keeps running.
Input Director seems to automatically 'deactivate' or windows on my client once I move back to main (or perhaps it simply mutes it?), is there a way to do the same for windows on my main when moving to client?
