We connected a Lenovo Thinkpad L13 Yoga and a Thinkpad T480 to this docking station.
The Thinkpad T480 has two Thunderbolt 3.0 ports. Nevertheless, it is the Yoga that works without any problems.
On the T480, the station keeps losing contact with the keyboard and the external sound card only delivers faltering sound. Interestingly, the screen has no problems (perhaps only USB?). The problems also occur when only the screen and keyboard are attached.
Has anyone had similar problems and know of a solution?

Question

Answer

Loss of contact could be remedied by updating the Thunderbolt drivers. The only problem now is the sound card. Unfortunately, I was not able to solve this by updating other drivers.

Answer

The latest firmware and drivers are installed.
