The first one shows the default behavior of pulseaudio when a new sound sink is added to the system. While your original report claims that nothing changed in the system.
The second link seems to be broken.My experience with digital outputs (connecting my speakers to a monitor) is that the monitor might disable the audio channel when the monitor enters in powersaving mode, so pulseaudio redirects the current audio streams to a different sink. And waking up the monitor might trigger the reverse redirection.
I haven't seen this behavior for quite some time now, though, but I'm using an analog output.
In any case, pulseaudio would need some kind of event to trigger the switch, either that a new audio sink is available or that the digital sink is not or is producing errors, something like that.
From the phonon perspective, I think that the issue needs to be reassigned to the pulseaudio maintainers, but you'll need to provide more information about it. Before that, it might be worthwhile to test once again using pulseaudio and the phonon's gstreamer backend.
