Description

Could you add a possibility to playback multiple audio tracks at the same time, using different audio devices?
Here's an example scenario in which this would be very helpful:
You want to watch a movie together with some other person. But while he/she wants to hear to her his/her native language's synchro, you want to hear the original English sound track. This would be no problem if you could output the different tracks to different devices.

Research direction

The issue names no files, tests, or entry points. Start by tracing how mpv selects audio tracks and output devices, then determine how simultaneous language-specific playback could be configured. Done means two selected audio tracks play concurrently through different audio devices, as described in the movie example.
