The sound of music??????

When I try to play music from itunes, the sound comes out of my laptop speakers instead of the sound system that I have connected to the ud-3900. 24 hours ago, this was not an issue and it worked fine. Any help out there for this?

Hi Jerry - With the docking station connected to your system and the speakers connected to the docking station, go to control panel > sound > playback device tab and select the docking station instance to be your default playback device by right clicking the instance and setting the check marks -> http://plugable.com/2016/01/15/set-de….
