Output 2 audio tracks simultaneously to different devices?

Question

Headphones

You need to output the sound from 2 audio tracks of the film (Russian + English) simultaneously to different devices - one track to the speakers, the second to the headphones. In stock TV, player Dune 4k Pro and audio receiver. I can replace the player with a PC if necessary.

Answer 1

Once in a similar situation, I searched for a long time, there are no ready-made funds.
I saved myself by launching two players with different settings (media player classic under windows) and suffered minimal desynchronization.
In one situation, I made a 4-channel audio file using ffmpeg, sequentially first extracted the tracks and then connected, when specifying the video codec as copy, the process is quite fast, and to play on different output devices (speakers and headphones), I simply inserted the headphones as 3 and 4 columns and turned on the quad in the operating system settings.

Answer 2

For example, Microsoft Media Foundation. Create 2 audio renderers . Only I can’t imagine which computer outputs speakers are plugged into, which headphones.
