I have a prop with an audio source with a VRC Animator Play Audio script and anytime an audio clip is "randomly" chosen and played, it's not the same audio clip to anyone who listens to it. So i.e. the prop plays sound 1 for me locally, friend A hears sound 2, another friend hears sound 4. As I think that's not intended, I would think the "random" playback order should choose a single random sound clip, which is the same clip heard by everyone who's in the vicinity.
