Running Fedora 40 on a desktop system with two monitors driven from built in graphics on motherboard (no separate video card). Yesterday I installed all updates including Plasma 6.2. I've noticed that whenever I turn on a monitor I get a notification sound that I've never gotten in the past. It's basically a two tone chime. I've searched through all the notifications in the system settings app and cannot find one related to this. I can't even find the sound file with the same sound. I've had no luck with google nor KDE bugzilla.
What have I missed? Where is this new notification specified? I'm assuming it has something to do with the Plasma 6.2 update.
Thanks for any pointers.
