I have a friend who works in game development for the Occulus, I can ask him if there’s a way of cleanly ripping the audio files.
Update: he says it’s difficult to do that on the Quest version because it’s Android-based, but he can help if it gets released for the Rift, which is PC-based. But if someone knows their way around Android software, it’s still possible to access the files, he just doesn’t know how personally.
