Windows 7, fully patched
Lenovo ThinkPad T460S laptop
Latest Plugable Displaylink Drivers are installed - Ver 8.2
Connected laptop to USB dock, the video works fine. However, when I click on Playback Devices, the Plugable sound option is there, but it is grayed out. The sound only comes through the laptop speakers; it is not transferred to the external source.
In this case, the external source is a large wall-mounted LCD TV that is connected to the USB dock via HDMI.
Already removed/reinstalled. Same issue. HOWEVER, it works fine on an older HP laptop.
