Behavior:
When launched, first checks if sound blaster exists. If it does, it restarts the program to bring up the window (otherwise, it is impossible for autoit to make it visible). Otherwise just start program. Then, it does its own version of hiding the window (otherwise it is impossible to re-show it). Now whenever the switching hotkey is pressed, it quickly shows the window, clicks the toggle key, then hides it again.
To download, either get the exe or compile the au3 with autoit...
