I am currently using your UD-3900 with a Surface Pro 3, in a MS docking station, along with 2 24 inch monitors and a 43 inch TV. I am having a problem with getting audio out to the TV using HDMI, video works just fine. I have gone into the sound settings, playback devices, but it does not show my TV at all in the device list. I have already made sure that all my audio/video drivers are up to date, as well as the firmware on my Surface. Any suggestions on how to get audio out to my TV?
Thanks in advance,
