Use case for having a second monitor enabled while gaming...?
The most annoying "game uses wrong device" issue I ever had was the Linux version of Transistor picking the wrong speakers. I launched the game and the sound was too quiet. Turned up the volume knob on my speakers and it was still quiet. Turned off my speakers and I could still hear it. The sound was coming out of the built-in speakers that I didn't even know my monitor had. It was wild.
Fortunately it was just a matter of putting a magic number in a cryptic text file.
