Swithching duel language

I have a Sony BDP-BX37 DVD player that I use for Serviio. I have a movie that is dual language and am able to play in English on the computer, but not in English on the TV. I can't find a way. Anyone know?
Thanks

What is the file format?
Does this file is delivered in native format or transcoded/remux ?
When transcoded/remux, only th first audio track will be kept.
If its an mkv, you can remux the track order with mkvtoolnix tool.
