http://api.kde.org/kdesupport-api/phonon-apidocs/phonon/html/index.html Doesn't list any classes, namespaces, or anything, really.
An older phonon API seems to be listed here : http://api.kde.org/4.0-api/kdelibs-apidocs/phonon/html/index.html but replacing 4.0 with any other number doesn't seem to work. What's going on?
Phonon documentation (in the KDE Frameworks 5 era) is at https://api.kde.org/phonon/html/index.html
