As it turned out Pulseaudio is sending the audio device to sleep which in turn brings the whole Dock down. In order to avoid this I had to comment the below module out and restart the machine.

### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle

Dock has been working fine ever since. After having used the machine for a while I couldn't determine any adverse side effects on battery life.

I am experiencing the same with a Dell Inspiron 5502 laptop, Dell D6000 dock and Ubuntu 20.10.

The latest DisplayLink drivers are installed. I will disable the PulseAudio module per your instructions and test.

Resolving this issue would be such a relieve.
