Having an issue when I play on multiplayer online and the sound level cuts about 20-30dB. The worst part is, it randomly comes on to regular sound levels for a few seconds on occasion so if you turn it up to compensate you get a blast to the ear drums at random. Also, the online chat doesn’t seem to experience the same cut so when you have people talking they are loud but you can barely hear your vehicle and other in game sounds. I’ve restarted the console numerous times and played on several different occasions now so it’s consistent.
On another sound issue, when you play career mode, the money counting sound will not stop once your credits have been applied from a race and continues even into your next race until you restart the game. seems to happen every 3-5 races. This is an issue I’ve only experienced on Xbox One X. I did not previously have this issue on the standard Xbox One.
