I recently deleted and reinstalled the game and still have the same issue on Xbox Series X. The sound in the game is super quiet. Its normal sound when game first boosts up, but soon as I'm in game it switches to quiet.
When I go back to my Xbox dashboard and select to quit The Crew 2 the sound then switches back to normal sounds.
Hey there, Poetic03! Sorry to hear you're having some sound issues in the game. I recommend going through our basic Xbox troubleshooting steps to ensure everything is updated on the console. Secondly, check to see if your levels are Default (to start out with) by navigating to the sound menus. Let me know if you hear any improvements.
