The problem is I have no clue how to do that! I'm not a direct user of
ffmpeg: this is Kodi which uses it... When I see how many options ffmpeg
have, this is obviously a complex tool ;o)

If you can explain me how I can read and send the audio stream of a video
file, using ffmpeg of my NUC running LibreElec, switching from passthrough
to 5.1 internal decoding, well, I can give a try.

I don't have any laptop I can use to make some tests...
