I need to check if this is reproducible. I had my main speaker muted, and connected my bluetooth headphones. They were displayed as a headset and connected, but the popup when switching audio devices did not appear. Also, the device was not shown as an option for the audio sink device. When disconnecting the headset, unmuting the speakers, and connecting it again, it was displayed as a headset and shown as a device. But it was not shown as a dropdown option but a parallel device, this may be something weird with pipewire. I am using EasyEffects Flatpak in the background but never had issues with that.

This behavior is governed by the audio stack below us: PulseAudio, PipeWire, Wireplumber, and/or Bluez. You'll have to debug there, or ask your distro for help. There's nothing KDE can do about this, unfortunately.
thanks, I report to Fedora then!
