Hello I'm back here and also back on Linux, even though I've been back and forth I think I might stay here for good now.
I've somehow got sound to work now, which wasn't too difficult to do!
Possible fix(not completely sure it was this): Try and install the oldest Proton, let it install its dependencies and raise the version or go back to 5.0-9 again.
I think just removing the installed proton and letting it re-install itself will do the same thing.
Changing the version of windows from win10 is the thing that actually fixed it.
Sadly(for me) my graphical errors remain, but does go away with the drivers from AMD open source, with lower fps as a down-side.
