Here, Nev, here is that scene with 5.1 audio. It’s a first attempt, and so if you have feedback and are interested in making it better, let me know. The sync is not identical to the clip you provided, so you are aware.

Hmm, it sounds like the central channel is missing.
Other than that, it sounds good 😉
Try the mkv I just added. The mov file is for editing rather than viewing, with six separate mono tracks that together comprise the 5.1.
There are certainly flaws here, so again, if this is something you want to develop further let me know.
