I am now also reminded of this "feature", which was a patch in 16.04 and seems to be an upstreamed feature in 17.10:

https://git.launchpad.net/~ubuntu-audio-dev/pulseaudio/tree/debian/patches/0100-switch-on-port-available-Switch-from-HDMI-to-analog-.patch?h=ubuntu-xenial

Not sure if it's related. That module "switch-on-port-available" is definitely one that Ubuntu uses but is not mentioned in the documentation:

https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/

So I'm not yet sure what it's meant to do.
