Does anyone know if the audio track can be changed?

I recently bought a new TV (Samsung) which has the capability of playing user iptv links via the smart iptv app. The developers have a website http://siptv.eu for converting your files for use with their app.

I've noticed that the audio track can be set when using the app with LG tvs so I was thinking it may be possible on enigma2.

Has anyone any experience with the smartiptv app & an LG tv?
