I am also working on tutorials, First , I'm curious why i cannot start a thread to address my problem,.... Why did I join this forum? Anyway, I am having similar problems. In my video tutorials, I wish to have sound from the application (Reason 4.0) and sound from my usb headset mic. Simultaneously I am on Windows Vista/Realtek card and all devices are enabled and functioning properly. I can record the video with sound from Reason, or sound from mic, but not both at the same time. I have tried almost every combination of settings and still no luck Any suggestions? Thank you, and I do apologize for hi-jacking this thread.
