PA and knotify startup race leads to wrong device selection

Bug description:
This appears to be a regression in Oneiric.
I'm running Kubuntu with pulseaudio.
I have on my motherboard intel hda analog audio and my graphics card (an ATI) had an HDMI out; by default I like the audio to come out of the analog output that is the only one connected.
Sometimes logging into KDE I find that it's decided to switch to the
HDMI as the default; today I caught it and did an lsof /dev/snd/* and
found:
knotify4 2276 dg mem CHR 116,3 6691 /dev/snd/pcmC0D0p
knotify4 2276 dg 20r CHR 116,33 0t0 9995 /dev/snd/timer
knotify4 2276 dg 21u CHR 116,3 0t0 6691 /dev/snd/pcmC0D0p
pulseaudi 2893 dg 24u CHR 116,9 0t0 6698 /dev/snd/controlC1
pulseaudi 2893 dg 31u CHR 116,6 0t0 6694 /dev/snd/controlC0
pulseaudi 2893 dg 38u CHR 116,6 0t0 6694 /dev/snd/controlC0
So knotify4 has hogged the analog output, and hence pa can't get in.
So I kill knotify4, and do a pactl exit to restart pa - but pa then
still lists the HDMI as the default output in paman, and I can't see a
way to get it back to default without restarting everything.
I'm also going to subscribe this bug to kde-runtime; I'm not sure who
is supposed to manage the race between pa startup and anything else,
and I'm not sure if it's a kubuntu special or KDE in general.
