title: Why does aplay work when pulseaudio is running and else not?
body: <p>I have a ubuntu install with pulseaudio default installed. When pulseaudio is running this works:
  aplay -D hw:2,7 /usr/share/xbmc/sounds/Bursting\ Bubbles/nav.wav</p>
  
  <p>But when no pulseaudio daemon is running it doesn't. The command doesn't give an error but I can't hear a sound.</p>
  
  <p>hw:2,7 is a Nvidia hdmi device.</p>
  
  <p>Why is this? I can't figure it out.</p>
