activar audio desde boton de dvd

[Lucho]

Hello everyone.
I need help with this dvd.
I have added the Spanish audio, and kept the 2 existing audios. I have changed the English subtitles for ones in Spanish.
I have modified the menu image, but by holding the English audio button (button 1) so that it now activates the Spanish audio.
I have looked at the navigation of the DVD, but on this DVD I am completely lost, I cannot locate where it determines the audio of the DVD, nor where it makes the audio change depending on the activated button.
I leave the backup of the DVD in case someone offers to help me.
All the best

Solved thanks.
