UI sound in general is much too low and muffled as opposed to all other sounds, which results in a constant and distracting need to reach the TV remote controller when a race stars (to lower the much harsher racing sounds…) So I either constantly adjust everything, or I simply leave the game as is thus missing out on probably good soundtrack and comments! NO SUCH PROBLEM IN GT7, by the way.
PLEASE CONSIDER ADJUSTING THIS sooner than later ; )
