Comment 135 for bug 198453

I think this is fixed by following change in pulseaudio

Version 0.9.10-2ubuntu7 :

  * Fix some errors in the pid file handling patch, thanks to Mandriva.
  * debian/pulse.conf: Do not use an absolute path when referring to the
    pulse alsa plugin, as this breaks bi-arch configurations. libasound2
    and lib32/64asound2 now include ldconfig files to include the alsa-plugins
    path for the architecture in use.
