Hello. i'm trying viewer 2 instead of emerald and i can't hear any in-world sound in viewer 2. i good example of this is if i click a sound in my inventory and open it. i have 2 options, play in-world and play locally. if i play locally i can hear it perfectly but if i click play in-world i can't hear anything at all. this applies to everything. object noises gestures and so on don't work but i can still hear things like the wind and UI sounds. Please help. Thank you.
