Merry Christmas everyone!

So I got FSX today. Got my X-52 with rudder pedals going. So i'm doing missions in FSX and I relize i'm not getting any sound from my so-called co-pilot. Didn't think much at the time. So then I jumped over to free-flight. I flew from Detroit Metro(KDTW) to Chicago O'Hare. I wasn't getting ATC voices, but I was getting the little words in the window. I messed with all the setting but still couldn't get it to work. Am I doing somthing wrong?
