OK, I am using another call, namely addAction(const QString&, const QObject *, const char *). Looking at the kactioncollection.cpp this looks fine. I checked it and the objectName() is set correctly, e.g. to "Increase volume Headphone:0 at ALSA::HDA_NVidia:1".

This sounds good.
But how can we progress from here? As it is now, the shortcuts break when changing to another language.
Is it still possible to change it for KDE4, or is it too dangerous?
If it is not possible, I could use a human readable form for my action names prefixes, like "PCM HDA_NVidia 1" instead of a cryptic "PCM:0 at ALSA::HDA_NVidia:1".
