I had fedora kde 41 all sound worked great. I upgraded to fedora 42 after a few update login sound quit working sometimes ,not all the time and shutdown sound and all others has always work just startup not working, but sound works when into desktop. I noticed that the sound icon has a red line when first comes up i wonder if sound is turned when booting now, i ahve it set to play login sound. I have a dell optiplex 7070. Is KDE turning it off or is kernel for just a split sec on boot into desktop. Thanks for any Help
There is a guide to troubleshoot sournd issues: How to troubleshoot sound problems :: Fedora Docs
Does that help?
