If I plug in headphones or speakers into the headphone jack on the docking station and play any audio, the audio is played through my laptops internal speakers and nothing else. While my computer, an ASUS Zenbook UX31E-DH72, is plugged into the docking station everything works except when I try to plug in either headphones or speakers to the headphone jack on the docking station. I am also experiencing the same exact problem of the headphone jack on my UD-160-A USB 2.0 docking station not working.
