Review request for KDE Software on Mac OS X, KDE Runtime, Phonon, and Solid.


Repository: kde-runtime


Description
-------

I'm trying to make the kcm_phonon Multimedia control panel more useful on OS X, so that ideally users will be able to choose different devices for the different playback (or recording) categories.

This RR outlines the current state of my draft attempt to provide that support. I'm handicapped by my lack of experience with both IOKit and Solid, and would thus appreciate a helping hand.

I'm currently at a stage where Solid returns a list representing the audio devices present in my system, but apparently not with the correct metadata for phononserver to consider them:

```
kded(81671)/phonon (kded module) PhononServer::findDevices: Solid offers 5 audio devices
kded(81671)/phonon (kded module) PhononServer::findDevices: Solid offers 0 video devices
...
kded(81671)/phonon (kded module) PhononServer::findDevices: groups: ()
kded(81671)/phonon (kded module) PhononServer::findDevices: already found devices: QSet()
kded(81671)/phonon (kded module) PhononServer::findDevices: Audio Playback Devices: ()
kded(81671)/phonon (kded module) PhononServer::findDevices: Audio Capture Devices: ()
kded(81671)/phonon (kded module) PhononServer::findDevices: Video Capture Devices: ()
kded(81671)/kded4 *Kded::loadModule: Successfully loaded module "phononserver"
```

Companion RR for the (required) changes to kdelibs:solid which is probably where most of the work will have to be done : https://git.reviewboard.kde.org/r/122404/ . That RR also has a full output log showing the available information about my devices.
