How to connect to a Windows sound output device, duplicate the stream and output it to tow physical sound devices (USB DACs)?

Hello. I've been told it can be done, but I can't find any way to do it.

This is on Windows 10. I have a regular audio player. I need it to play 2.0 music into a single audio device, and I need the sound to be split and directed to TWO different sound output devices. I don't care if the player outputs to a regular Windows device or to a virtual one; it could be a 4.0 device (the player then will handle duplication) or a 2.0 device that then splits the signal. I only need to:

1. Get the player to play into a single device (virtual or otherwise) and output to 2 physical devices; and

2. be able to apply channel-wise VST plugins to every channel separately. If you can create a 4.0 device then the player should be able to handle it; otherwise the backend splitter has to provide the ability to load and configure VST plugins.

Anything to do with Audiomulch? Very easy to do it there!

Erm... Why do you suppose I'm asking here? :)

I've been told AudioMulch can do it, but I couldn't find a way even if my life depended on it. Unfortunately, the person who told me that a while ago is unavailable for questioning.

Frankly, I find Audiomulch UI not very intuitive. But more importantly, I think I've looked everywhere around the program's interface, and didn't see anything that seems relevant to my problem. Specifically: how do I grab sound from one of the Windows output sound devices? I mean, there is AuxIn and SoundIn but that's not what I need, obviously.
