I have 2 DLCs, FNIX and Alpine Unrest.
I bought this game around the end of August, I have 15.6 hours invested on Steam.
Since I have bought this game, I have NEVER had audio for it.
I am on an Alienware 17 R4, RealTek Audio Drivers, NVIDA graphics (1070, if I recall)
I only have 1 default device for both output and input (not that the mic matters I guess)
I cannot find a fix at all.
