Hogwarts Legacy - Language Change

[weicg97]

Looking to see if anyone has found a solution to this issue.

My heroic launcher version is 2.20. I'm on a steamdeck (system language=english). When I started to download this game, it asked if I want to download additional content, which are different language packs. I have chosen Espanol (Mexico)

However, this was not applied for the game. I have changed the preferred language code to es. and I have added the flag -culture=es-419

This has changed the interface language but not the audio.

While I am on PC, adding the flag changed both interface and audio language.

Any ideas on what I need to change on the steam deck?
