Are u sure no sounds are in the game or in the Project window? Because this is maybe a bug if u have any sound files in your inventory some of them are maybe bugged or if u have any sounds in the game u should check out is the sound , good , as in working like it should be. I preffer u to make folders of the sounds and sort them in the subfolders like: M4A1, Grenade, Forest, Birds, that way u can keep the track of where your stuff is. IDK whats the problem here really, is your sound card IN the motherboard or is it just ON it? sorry if dont understand what i want to say…
