Bug 2279869

I cannot play CDs with Amarok because they are always shown to have 0 tracks.


Reproducible: Always

Steps to Reproduce:
1.  Insert an audio CD into the DVD drive in my computer.
2.  Wait for the system tray pop-up for new device "Audio CD".
3.  Either click on the option "Play audio CD with Amarok" (phrasing could be different, I use the German language pack) or start Amarok from the menu.

Actual Results:  
In the left column, a new entry "Music CD" pops up which says "0 tracks". I cannot do anything with this new entry except clicking the "Eject" symbol, which ejects the CD from the drive.


Expected Results:  
The new entry "Music CD" should show the list of tracks of the CD and I should be able to play the tracks.


The same issue also happens when Amarok is already open when I insert the audio CD.

I can successfully play CDs in VLC and Dragon Player and can rip the tracks in K3B. I can also open the audio CD in Dolphin.

I had already opened a bug for this issue at https://bugs.kde.org/show_bug.cgi?id=486517

I was told there that the problem is that Amarok is still a Qt5 application and, because of that, needs https://src.fedoraproject.org/rpms/kf5-audiocd-kio. But Fedora 40 no longer provides this package. It only provides https://src.fedoraproject.org/rpms/audiocd-kio, which I assume is the Qt6 variant of that module. 

Here is the log output of calling "amarok --debug" and then inserting a CD into my DVD writer:
