Great, thank you for filing this report! I've noticed some hints about this kind of problem myself & from other bug reports, but now that there's a specific report I can refer to, I'll be more probable to inspect & try to fix this sometime.
Comment 2 Tuomas Nurmi 2024-09-21 11:04:29 UTC 
Funny, I encountered this problem earlier, but now when I try to reproduce, it seems to work ok. I'll try and see if I still might be able to trigger this somehow...

Maybe the problem has now changed slightly. It may be more of a UI issue. Playing progresses through the cd tracks but the playlist still shows it as playing track one when it has moved onto subsequent tracks. The current track applet also doesn't update (at least for me)

Also if I drag 3 tracks from the cd into a playlist (when there are more than that on the cd, after track 3 it continues with track 4 ignoring what is actually in the playlist (with the current track still shown as track 1 - as above)
Comment 4 Tuomas Nurmi 2025-02-22 09:42:49 UTC 
Ok, might be related to phonon-vlc. I can reproduce with current Amarok git and Qt6 phonon-vlc backend.
Comment 5 Tuomas Nurmi 2025-02-22 10:03:51 UTC 
running with --debug-audio, playing track 2 almost starts, but phonon-vlc aborts and starts playing track 1 instead

PHONON-VLC BEGIN: virtual QVariant Phonon::VLC::MediaController::interfaceCall(Phonon::AddonInterface::Interface, int, const QList<QVariant>&)
PHONON-VLC   BEGIN: void Phonon::VLC::MediaController::setCurrentTitle(int)
PHONON-VLC     setting CDDA track 2
PHONON-VLC   END__: void Phonon::VLC::MediaController::setCurrentTitle(int) [Took: 0.12s]
PHONON-VLC END__: virtual QVariant Phonon::VLC::MediaController::interfaceCall(Phonon::AddonInterface::Interface, int, const QList<QVariant>&) [Took: 0.12s]
PHONON-VLC BEGIN: virtual void Phonon::VLC::MediaObject::play()
PHONON-VLC   BEGIN: void Phonon::VLC::MediaObject::setupMedia()
"PulseSupport(2): context_state_callback Terminated"
PHONON-VLC     setting CDDA track 1

Works now with the new gstreamer based playback engine https://invent.kde.org/multimedia/amarok/-/commit/56c7e43dd62ea67885423f26c9468fa7d1e3cc83
