Created attachment 474310 [details] emerge --info kalarm I realized that I hadn't sound anymore with kalarm alerts. Logs talk about phonon, so I recompiled media-libs/phonon-4.9.0 and kde-apps/phonon-kde-16.04.3. Now, when try to play a sound (test sound in alert config) I have : kalarm(25706)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded kalarm(25706)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded kalarm(25706)/phonon (KDE plugin): QDBusError("org.freedesktop.DBus.Error.UnknownObject", "No such object path '/modules/phononserver'") kalarm(25706)/phonon (KDE plugin): QDBusError("org.freedesktop.DBus.Error.UnknownObject", "No such object path '/modules/phononserver'") kalarm(25706)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded kalarm(25706)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded kalarm(25706)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::AudioOutput ( no objectName ). kalarm(25706)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded I wanted to try to add gstreamer to phonon (media-libs/phonon gstreamer), but it requires to remove gstreamer from qtwebkit:4 (dev-qt/qtwebkit-4.8.7 -gstreamer) and gstreamer just takes too mutch time to compile to test that now. I'll try it later if needed and if the idea to add gstreamer to phonon is the good one about you.
recompiled with new USES : media-libs/phonon gstreamer <dev-qt/qtwebkit-4.10.4:4 -gstreamer And sound works again in kalarm. May be media-libs/phonon[gstreamer] should be a requirement for kalarm.
phonon[gstreamer] is certainly not a requirement for kalarm. phonon can be configured with several different backends, vlc's being preferred.
never mind what solution is adopted. When you emerge kalarm, you want sound working. The solution I found, alone, is phonon[gstreamer]. Feel free to adopt another.
(In reply to Christophe PEREZ from comment #3) > When you emerge kalarm, you want sound working. Of course you do, but in your case probably simply rebuilding phonon was the solution. Did you recently get the upgrade to Qt-4.8.7?
