  Hello everyone, I did a late night upgrade yesterday from F34 KDE to F35 KDE and found myself with no sound devices available on my system. I've opened a BZ for that (https://bugzilla.redhat.com/show_bug.cgi?id=2018681), however it's quite difficult to use system with no sound and it may be a known issue already.

 As mentioned in the BZ, when I load system with Live USB (RC1.2) the system eventually get all devices listed, so I would presume it's some leftovers from the F34 installation or some config or state file that blocks the F35, but no clear indication which one is a culprit.

Any ideas what to try?
Best regards, Alex
