Description Martin Kho 2016-03-19 12:55:53 UTC

Description of problem:
No music, which is rather annoying for a media player ;-) The complete error message is:

amarok(6219)/phonon (KDE plugin): Can not create backend object from factory for  "GStreamer" ,  "phonon_gstreamer" :
 "Could not find plugin 'GStreamer' for application 'amarok'" 
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded

Settings -> Configure Amarok -> Playback -> Configure Phonon -> Device Preference is empty. The Front Left and Front Right buttons (Audio Hardware Setup tab) are working correct.

No problems with sound in other applications.

Same problem here. Running into debugging mode gives this warning.
--

try,

Comment 3 Rex Dieter 2016-04-19 19:29:30 UTC

or possibly,
https://bodhi.fedoraproject.org/updates/FEDORA-2016-d3a880fb8c

we're sorting out a qt4 plugin issue for some stuff built erroneously by gcc6

*** This bug has been marked as a duplicate of bug 1327360 ***

Comment 4 Rex Dieter 2016-04-20 10:09:44 UTC

amarok, phonon, phonon-backend-gstreamer all have the proper qt buildkey now:
buildkey=x86_64 linux g++-4 full-config

So, it's problem is apparently something other than the issue tracked in bug #1327360  , re-opening

Comment 5 Rex Dieter 2016-04-20 15:32:45 UTC

See latest bug #1327360 , comment, but it would appear the latest batch of builds in fact did not fix the problem (but introduced yet another different/incompatible QT_BUILD_KEY).  

Short version: this issue is (still) probably a dup of bug #1327360 , but I'll double/triple check it this time before marking it as such

Comment 6 Rex Dieter 2016-04-20 23:16:52 UTC

confirmed fixed qt/phonon takes care of this, remarked as dup, updates coming soon
