I recently purchased a NuForce Udac-2, for my Dell Inspiron laptop - Windows 7 64 bit operating system. After going to NuForce's website and following their setup instructions for Windows 7, I was able to get the Udac-2 to work - testing my headphones while on Youtube.
I then tried to play a movie on DVD, using Windows Media Player, and had no sound on my headphones, using the Udac-2? What am I doing wrong? Any help setting up the Udac-2 is much appreciated.
