Support Ubuntu 20.04 LTS (Focal Fossa)

I have recently upgraded from Linux Mint 18.3 (Ubuntu 16.04) to Kubuntu 20.04. The improvement I see in DisplayLink behavior is noticeable: no more screen corruptions even if I use the OpenGL compositor and VSync, for instance, and no apparent performance issue (the video seems to work just fine, like if I had the monitor connected directly to the HDMI port of my notebook).

However, what is not working is audio: even if I have the output in Kubuntu audio panel ("USB3.0 Dual Video Dock") and even if I try to change the output profile to anything listed there (from digital stereo IEC958 output to analog stereo, 2.1, 5.1, what else output), I hear no audio neither from headphones connected to the audio jack in the front of the docking station, nor from the speakers of my monitor connected to the docking station through HDMI.

Has anyone this problem?
