My audio 2 installs correctly and is recognized. I use a vestax VCI-100 controller and an audio 2 DJ sound card by NI. No sound plays when I play music through Traktor 2 when I have my Traktor Audio 2 sound card selected. I go to the sound card control panel and it says "No Streaming Possible." Any ideas how to fix this or recommendations? I have been tried uninstalling and reinstalling. Have changed my default soundcard... alll kinds of stuff.
