Windows. Is it possible to force a specific application to use a specific audio device?

Question

Audio

Hello,
There is : A PC with a Radeon 270x on board and Windows 10. Connected to it: 2 monitors via DP and DVI, as well as a receiver via HDMI. Headphones are plugged into the monitor connected via DP.
With this scheme, you can manually select which device to output sound to, overriding the default device.
Problem : sometimes you want to drive some skyrim with headphones while the girl is watching the next show on the speakers (one of the cases).
Notes : The sound goes completely through the video card, because. the built-in audio controller is dead a little less than completely.
Vidyashka can do DDMA, i.e. can output 3 independent audio streams.
The video is watched mostly online.
I tried audio output switcher - specifically on my hardware and in my OS, all sound goes to the device for which the last rule is specified.
Question: How to bind a specific application to a specific audio device? If not possible, then how to force any of the browsers (or flash player) to use a specific audio device?

There is no solution and will not be until Microsoft implements it. To realize this possibility in Windows, you need to climb into the kernel - this is a violation of the license, Microsoft will sue. Therefore, no one develops such software. Craftsmen do not do it - because it is difficult. A team of specialists is needed, and they need to be paid money, which means the project needs to be made commercial, which means Microsoft will sue (although in any case it will sue, because this is again a violation of the license, even if not a commercial project). DEADLOCK :-(
This functionality is implemented in Linux (by third-party software). I heard that MacOS has the same thing. I haven't seen it myself.
