Sometimes when I boot up my system (happens around every 2 - 3 days) and I login into KDE Plasma it doesnt recognize any of my input and output audio devices. The Tab in Settings > Audio is also completely blank. Also the whole desktop experience is very laggy and e.g. youtube videos take forever to load. But when I reboot my system, everything works fine again my audio devices are being recognized by the system and Youtube Videos are able to load. The next few startups work fine but around every 5th startup the problems start to appear again randomly and I have to reboot again.
Ive also noticed that the output of journalctl -x -b -p 3 is different when is issue occurs:

as startpoint, you could fetch a complete dmesg output from a good and a bad startup, and post it here.
It would be good to have it from the same day, without any system modification (update, new software install, no other hardware connected)
Same conditions? It's always a cold boot ? No ms windows is started between ?
