From time to time, the sound crashes. All sound options (devices) disappear.
When I disconnect my docking station from my PC, then the sound option (devices) comes back.
Therefore, I think DisplayLink is the cause to this bug.
Similar problems also happened on Ubuntu 22.04.
This a new problem. Most probably is related to the release 5.8.
Does anyone have similar problems and got a fix?
I will try to downgrade the driver when I get time.

Out of curiosity, if you disconnect all of the external devices connected to the docking station itself (for example, keyboard, mouse, webcam, etc.) and leave only the dock's power cable and USB cable, does the behavior change?

I ask because I am curious if an external device connected to the dock (and not the dock itself) is contributing to the unexpected behavior.
