Simultaneous playback of two audio tracks?

Question

media players

I really need a video player (for learning a foreign language) that could play two audio streams at the same time. Quite ideal if the player also shows two subtitles.
Old versions of Light Alloy seem to be able to merge audio tracks, but somehow they do not digest mkv files with embedded sounds and subtitles.

Answer 1

Audio tracks - VLC, for example. Media - Advanced Open File - Show more options.

Answer 2

In this case, BSPlayer will help - in the “Audio streams” in the “Audio stream selection” window, specify which tracks of the BSPlayer video file should play simultaneously .
