No Sound Issue T440P

Hi All,


We have recently bough two T440P laptops and two Thinkpad pro docks 90w for staff members.


The laptops all have Windows 10 64bit OS installed, and the latest drivers off Lenovo Website . I tested the sound equipment they both works fine.


Sadly both Laptops cant play sounds once docked.

Dock1 - HDMI - Will display the image, recognised in playback devices but no sound comes out the speakers connected to the dock.

Dock2 - 3.5MM Jack - Will play sound when directly Plugged into the Laptop BUT not through the dock.


I have tried upgrading the Firmware for the Dock no luck... any suggestions?


Kind regards

James Sewell
