Dual U3415w Audio

Hello,

I have two U3415w's connected to a Lenovo docking station. The docking station has two Displayports and one HDMI. Display #1 is connected via HDMI from dock to the monitor, display #2 is connected via HDMI cable to a DisplayPort adapter then to the dock. Video is flawless on both but I can only get audio from Display#2. Drivers are up to date.
