Got my 1st bug to report (I think) patch 4 (wasn't present patch 3).
Possible sound issue, XB1X, Samsung 5.1 surround, Ferrari 488 GT3, Brands Hatch.
Randomly all game sound goes very quiet for a few minutes then comes back again to normal volume.
Had it happen a couple of times now, at 1st I thought I lent on the TV remote by accident.
Doesn't seem to happen on any other track/car combo as yet. I'll keep testing.
Does this happen all the time on that track? I think I had that happen once too after patch 4.0 or 4.1
I think it was brands hatch in the gt5's. I allocated this to me being intoxicated but there might be an issue there
