Just one more description, for information... My bug is a crash of gnome that redirect me to login screen, not a full reboot. So the shutdown information at the end of the "prevboot.txt" are not related to the bug.

When i log again, the only "sound output" allowed is simulation, my devices are not displayed. I'm using - Ubuntu 20.04 (I upgraded from 18 some months ago, I don't think this bug was present at that moment but i used less my ubuntu station). - Portable PC The bug happen - When I use my PC with screen pluged directly : some times - When I use my docking station with 144Hz display in DVI (https://i-tec.pro/fr/produkt/u3hdmidvidock-4/) : quite frequently - When à Use my docking station and watch some full screen video : very frequently It seems to be linked to displayLink use, but not only because it happen too when i don't use the docking station. It seems to be frequently when i "Stress" the screen.
