Possibly relevant? Not sure what this means though.

It means certain codec is missing from the winegstreamer build included with Proton. There's other discussions where H.264 codec has been mentioned so it's not specfic to this game, there are other games with same thing. There is code to decode it, but distribution of it is another thing.

try proton ge, have a solution for this

Proton 7.0-4 starts and game is playable. However, after starting new game only voice is heard during cutscene. Game works after this.

With Proton experimental videos are working.
