As requested, I will post my questions in the generic modding section.

I have just read your explanation on the Menu/Ingameannounce.menu, but I have failed to create something successful so far as I do not have much knowledge about the TE engine that regulates sounds and the difference existing between the Audio FX Number
and the Audio FX Sub Number.
Therefore, I would like to ask you if you could please provide me with some more practical examples like you did with the 'Low Applause' example.
You also said that the idea of that new system consisted in substituting 'default' sounds by new ones in some cases. Does this imply that we have the possibility to add brand new sounds with no need to use them as a replacement to 'default' sounds?
Thank you in advance!
