windows 10 has a feature that let's you change the audio device individually
I can have firefox to only use my P2 headphones and have google chrome to only use my HDMI monitor speaker
the major problem with windows 10 implementation is that the program needs to be open and using the audio device to change it;
is any audio is playing, I need to go into settings app, sound setting, adapter settings, and select from the list

my suggestion here is to have displayfusion to handle that the same way it handles window position profile
let me pick from a list of any and all programs that use audio and change which device will it use
