"Yea [...] but no it not", your english is - at least for me - very difficult to decode and understand.
So again: In the list of audio device recognized by windows, did your DDJ800 show up there?
Another question: In a former posting you wrote that you already tried the asio plugin (the one of OBS?) but didn't succeed on that. Do you know that, if you try to go the asio way (its a completely different driver architecture) you have to use an asio driver for your hardware. So did you download an asio driver for your DDJ800, too?
