Title:
  libao defaults to ALSA output, should probably use Pulseaudio

Status in libao package in Ubuntu:
  Confirmed

Bug description:
  When playing sound from an application that uses libao on Ubuntu 12.04
  (for example, pianobar), it blocks any other sound-playing application
  from playing audio (for example, Firefox on YouTube).  A little
  digging showed that /etc/libao.conf sets default_driver=alsa, changing
  this to default_driver=pulse makes simultaneous audio from multiple
  programs work perfectly.

  1) Ubuntu 12.04
  2) libao-common 1.1.0-1ubuntu2
  3) Expected audio to play from several apps simultaneously
  4) Apps using libao block the sound card so that no one else can play sound
