It takes fairly little effort to set up Jellyfin. I think there’s scripts these days that set up the entire arr stack for you in a matter of minutes.

Maybe just quickly check what Steam’s audio player has listed as soundtracks, just to rule it out (assuming you haven’t found the cause yet).
Last time I heard about weird audio playing it was Steam’s built-in soundtrack player picking up all kinds of weird stuff and randomly playing it (or getting triggered through some shortcut or something)… just to rule it out, do you have Steam installed?
Most Nazis historically were.
Personally it’s quite nice. I just request what I want to watch and the system grabs it automatically. It can download from Usenet too.
