Hallo everyone!
I’ve fixed it!
I’M SO HAPPY 
What i did was upgrade to the latest kernel (6.0.2-2).
After that i saw multiple sound cards pop up in pulseaudio.
And now if i select the pro 5 i have audio from my speakers!!
I have however no Idea why this worked and what ‘pro audio’ is while stereo output flags are all unavailable (first image).
Can anyone here please explain me what is going on ?
Thanx!!!
