I found that it works with the old SDL2.dll (2.28.0) which I've been using for a while, but not with the SDL2.dll which comes from the CI (2.30.0).
EDIT:
The crash is happening when calling SDL_ConvertAudio with the new SDL2 2.30.
EDIT2:
The regular music plays, so this is either something specific to the sound format that the particular video uses, or any mistake in sound processing that did not cause trouble until now.
