Sound glitching out on certain tracks

I noticed a bug over the past couple of days (just got the game) that the sound would glitch out sometimes and car noises would just stop playing for a second and then come back, and there would be ticking noises and overall audio chaos and I now have realized that it is on the Top Gear test track full. Does anyone know why its doing this only on this track? Other tracks get the audio ticking noise but it never cuts out entirely at random for any other track so far.

edit: and it seems to only occur when im near a lot of other cars.

The weird sounds were stronger on the TG test track, that’s true…especially during the London challenges. Never understood what’s the cause of those sound issues.
Anyway, to fix all of this, make sure to quit the game after getting back to the dashboard (Press START and then click on QUIT).
