Typically Pulseaudio is started on-demand by applications that use it.
On my headless server, Pulseaudio is not running after boot, but when I
launch the music playback server (MPD), it runs as my user.

So, what is starting Pulseaudio in this case?

Hi Leo,

I had a spurious '-soundhw hda' in the qemu call.

Thanks for asking the obvious question ;-) - George
