  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.
