How to create two independent audio outputs from different sources in Windows 10?

Question

Audio

Introductory: there is Win10. Installed Google Chrome and everything else (Telegram, Slack etc.).

Task: listen to MPCHC through the speakers at the same time, and everything else - as a separate stream through the headphones. For example: we watch a movie with sound through the speaker system, and at the same time we launch videos from YouTube or an audio message from Telegram, which are heard only in headphones.

Question: how to implement correctly?

Answer 1

In your case, you can use the settings of Media Player Classic, which allows you to determine through which speakers which channel is output, lowering the number of columns, for example, stereo output to a pair of quad speakers.
Settings - built-in filters - Audio switches, add channels and mark the two you need.
In the windows settings, you need to enable quadraphonic output by connecting headphones to the front speakers and speakers to the rear speakers.
Control Panel - Sound - Customize (as I understood later, you can switch it back to stereo either).
The fact is that when I set it up, I did everything using the regular realtek utility, but in recent years it has been excluded from the supply, so your experiments are on.

Answer 2

Windows 10 already has this feature "App volume device preferences".
But to separate your outputs into speakers, ears, and the like - that's another question.
You need independent DACs for these devices.
For example, devices such as the built-in Asus phoebus card (out of production, I don’t know - there seem to be analogues).
or products from RME (very expensive).
Another option, for example, is to put the headphones through the connectors in the computer (DAC in the motherboard), and other devices through any simple sound card (external or internal). And then in Windows it will be possible to select a specific application on Output "x" or "y" and play them simultaneously.

If the sound box is from Realtek, then it's very simple. It allows you to redefine any connector from the driver. We actually connect speakers to one of them, headphones to the other, the default sound output to the ears, and redefine it to speakers in the player.
