First thing, love RaceRoom, have most racing sims but like this the best, so my question, the sounds in this sim are the best out there, period, but when i play using my 5.1 av setup, cars coming up from behind, then either overtaking left or right, i dont hear this from my rear speakers, and i have enabled 5.1 in sound settings, and anyway, i hear other effects like the gravel under the car etc, in Dirt Rally you can clearly hear cars coming up from behind and then passing either left or right, i do hear a very faint car sound in rear speaker, but not like it should be, is this a known problem, or just how its meant to be, cheers
