Just bought this game And can’t hear all the sounds.. disappointing

First time trying to play this after buying and downloading it today and can’t hear the characters talking or other things, only sounds like them walking and other background sounds can be heard, I’ve looked up fixes and tried those but no luck. Very disappointing as now the game won’t be enjoyable. Is there any hope here before I ask for a refund? FYI I’m playing on a XBox X
