<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The solid audiointerface stuff is gone in frameworks5, so ultimately this is a dead end. Equally phononserver is bound to go away at some point in the future and being replaced by listing exclusively what phonon reports (which in turn is pulseaudio listing || backend listing). So, enabling VLC to expose this information through the libvlc_audio_output_device enumerable would be the best course of action. If the VLC devs don't want that or whatever, then putting it in Phonon seems the most useful approach.</p></pre>

I'm not quite motivated to invest in learning IOKit at the moment, and Solid even less.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Pulseaudio is a bit problematic on OS X currently, and I've seen many complaints about it (e.g. concerning delays that I can confirm on my Linux systems where event notifications tend to sound "long" after the event).
So the best course of action might yet be to figure out why the vlc backend isn't in MacPorts.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Is phonon-backend-vlc still/indeed the preferred backend for KDE/KF5?</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">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.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">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, despite the fact that I pretend all devices to be pluripotent (i.e. AUDIOCONTROL|AUDIOINPUT|AUDIOOUTPUT) :</p>
