--- Comment #70 from demurgos@demurgos.net ---
or understand why it worked once with the native xaudio2_7.
I was able to reproduce it: the game starts and dialogues work with the native xaudio2_7 if I start it in windowed (borderless or not) mode with the smallest resolution (800x450). I don't know how the resolution is related to xaudio2_7 but at least I know how to start it. (Obviously this is not ideal though).
If I run it fullscreen or with a larger windowed resolution with native xaudio2_7, it crashes.
