When trying to set volume from amarok or dragonplayer, nothing happen. Reproducible: Always Steps to Reproduce: 1. Have pulseaudio4 installed 2. launch amarok or dragonplayer 3. try to change volume Actual Results: Nothing happen Expected Results: volume changed downgrading to phonon 4.6 fix issue

Git commit f278a93493ac04ce04d48e8e5b5158caa0621ce3 by Harald Sitter. Committed on 07/11/2013 at 15:16. Pushed by sitter into branch '4.7'. Ensure the PulseAudio envrionment is set up when running older backends This ensures that pre-4.7 backends (expecting the environment to be set up by libphonon) retain working volume control. FIXED-IN: 4.7.1 M +2 -0 phonon/audiooutput.cpp http://commits.kde.org/phonon/f278a93493ac04ce04d48e8e5b5158caa0621ce3
<apachelogger> you have to update phonon-gstreamer/phonon-vlc as well <gnumdk> apachelogger: using ArchLinux so up to date ;) As i was sure Kubuntu was not broken, i tried to downgrade phonon As I said, please make sure you have phonon-vlc 0.7.0 installed.
gnumdk@arch:~$ pacman -Q|grep phonon phonon-qt4 4.7.0-2 phonon-vlc 0.7.0-1
Applying your patch fix issue.
The backend was not built against libphonon 4.7.0 then. When built against libphonon 4.7 the cmake output of the backend should contain "Building against Phonon 4.7 API", otherwise it won't use the new interfaces for PulseAudio setup. You may want to report a bug against Arch I suppose.
I can reproduce the same symptoms using phonon-4.7.0 and phonon-backend-gstreamer-4.7.0 (confirmed built against phonon-4.7.0), though it's build output doesn't mention anything like "Building against Phonon 4.7 API" testing the referenced commit now...
pgst doesn't mention what API it builds against
oddly enough, * using a patched phonon per commit referenced in comment #5 seems to help * rebuilding pgst again, seems to help too, and it's no longer reproducible. curse you gremlins
Found the problem. I have not the slightest idea how it can work for some builds and not for others.... oddest thing in the world.
Git commit 6d6889ea87d10aac2a3627cc98ddd8d308974952 by Harald Sitter. Committed on 12/11/2013 at 12:53. Pushed by sitter into branch '4.7'. use backend_version define as option for automoc + debug API target otherwise classes may get moced with the wrong interface version setup. also imported API target debug from VLC to make it obvious in the cmake output what API target will be used.
