After installing Fedora workstation 40, the sound output is not redirected automatically to headphones when they are plugged in. When the headphones are unplugged, the sound also has to be manually redirected to the speakers.

From Proposed Common Issues to Ask Fedora
I have the exact same problem on my Fedora 40 laptop.
The output device does not switch automatically when headphones are plugged in and I need to do it manually.
I wrote a bug for this a while back, see
https://bugs.kde.org/show_bug.cgi?id=486272
In my bug the “not switching to headphones” was mentioned but was just part of the problem. I would plug in the headphones the Pulseaudio Volume Control “Output Devices” would have the headphones in the list but would not automatically switch. So if I manually selected the headphones, the playing video would not play in the headphones. I had to manually run:
systemctl -l --user daemon-reload; systemctl --user restart wireplumber pipewire{,-pulse}
to restart the pipewire/wireplumber. The sound would then play but there would be a nasty plasmashell core dump/crash. So Bug 486272 is mainly about having to restart pipewire and getting a plasma crash but a side issue is why is the output device not switching.
This should also include a “Default Audio Device” setting that when bluetooth or other non-local speaker is disconnected the sound dialog either demands your choice or defaults to aka laptop speakers(internal sound)

I have a Fedora 40 laptop (the one I wrote that bug for: 486272 – switching to headphones by restarting pipewire and wireplumber causes plasmashell crash ). When I plug in my 3.5" wired headset, the pulsaaudio volumn control “Output Device” menu blinks and I see the “speaker” go to “speaker (unavailable)” (or whatever similar wording, I can’t see that laptop now) but it doesn’t autoset to “headphone” as it should. I have to manually select the headphones as the Output Device but even then it doesn’t play the sound (the video is silently playing).
Then I have to resort to restarting pipewire/wireplumber, then plasmashell then crashes but from then on the video plays okay. I need to try again with KDE 6.1.3 since that update just came out on Fedora on July 21
