You have been subscribed to a public bug: I've been using Kubuntu 16.04 since it was released, and have been using Amarok to play MP3s without any issues, until yesterday. After installing some updates:

I ran Amarok with the --debug command-line argument, and this is what happens when I double-click a MP3 file in the playlist: amarok: BEGIN: void Playlist::Actions::play(const QModelIndex&) amarok: BEGIN: void Playlist::Actions::play(quint64, bool) amarok: BEGIN: void EngineController::play(Meta::TrackPtr, uint, bool) amarok: BEGIN: void EngineController::stop(bool, bool) amarok: END__: void EngineController::stop(bool, bool) [Took: 0s] amarok: [EngineController] play: bounded is QObject(0x0) current "Crystalised (Epicleptic remix)" amarok: [EngineController] Just a normal, boring track... :-P amarok: BEGIN: void EngineController::playUrl(const KUrl&, uint, bool) amarok: [EngineController] URL: KUrl("redacted path to MP3 file") "redacted path to MP3 file" amarok: [EngineController] Offset: 0 amarok: END__: void EngineController::playUrl(const KUrl&, uint, bool) [Took: 0s] amarok: END__: void EngineController::play(Meta::TrackPtr, uint, bool) [Took: 0s] amarok: END__: void Playlist::Actions::play(quint64, bool) [Took: 0s] amarok: END__: void Playlist::Actions::play(const QModelIndex&) [Took: 0s] amarok: END__: void Playlist::PrettyListView::trackActivated(const QModelIndex&) [Took: 0s] amarok: [EngineController] slotTrackLengthChanged( -1 ) amarok: BEGIN: void ProgressWidget::redrawBookmarks(const QString*) amarok: END__: void ProgressWidget::redrawBookmarks(const QString*) [Took: 0s] Calling appendChild() on a null node does nothing. I can play Ogg files without any problems, as I realized when I deleted my Amarok configuration and restarted it -- the default playlist contains a sample track in Ogg format. ** Affects: amarok (Ubuntu) Importance: Undecided Status: New ** Tags: gstreamer -- Amarok can no longer play MP3s after gstreamer update https://bugs.launchpad.net/bugs/1661739 You received this bug notification because you are a member of Desktop Packages, which is subscribed to amarok in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
