11-27 update broke audio

Played the game for the first time yesterday morning and everything was fine. Then when I played it last night the audio was much worse. What ever happened gave me the same issues I got when I first got the creators update for windows. The game sounds ok in the in car views but and view outside the car sounds like it is being filtered through a giant tin can. It gets progressively worse the more races I complete in one session. Half the time by race 4 the audio badly stutters and sounds like that tin can the audio is coming out of was moved miles away and placed in a giant empty tin warehouse for an even worse echo. I don’t know what happened between yesterday morning and last night but the audio went from not good to broken. It is just so bad. At times it sounds like you are sitting in the car as it gets sandblasted.
