Can confirm. I live in a region with the version "Second Life RC Ferrari 2023-12-06.7120498618
The issue happens whenever I collide with anything in my house. The sound doesn't even come from the right place either. It comes from the origin of the prim rather than my avatar.
Using the llCollisionSound function in a script also has odd behaviour. If I set the sound to blank, and/or volume to 0.0, it still plays the improper sound at full volume. However, if I set a different UUID for the sound, it will play that sound instead, still at the improper location.
