Had to create an account so, I can post in this thread for more visibility. I have same issues as you mentioned, to add more information I play coach coop on base PS5 installed internally (3D sound is off, I use eARC with Soundbar).
All below bugs can happen separately or all in once. Happens in most of dialogues.
1. NPC Dialogue animation just resets and it is super jittery.
2. No sound in dialogues
3. Sound delays in dialogues that don't much animations
This kills all the joy of the game and all dialogues are joke. Feels like I am playing beta version of the game.
Waited for over a year to purchase Baldurs Gate 3 in hope that there will be less bugs and it will be more polished
