** Project changed: media-hub => pulseaudio

** Description changed:

  I keep on receiving bug reports about Machines vs. Machines being crashy
- and I tracked it down to the SoundEffect item. When playing without
- sound effects enabled, the game seems very stable.
+ on Ubuntu Phones and I tracked it down to the SoundEffect item. When
+ playing without sound effects enabled, the game seems very stable.
  
  To get to the bottom of this I created an app that simulates a bit how a
  game works with sound effects. It's a bit more aggressive than Machines-
  vs-Machines (still not really far fetched from a real game scenario) and
  reliably triggers some crashers in less than a minute here.
  
  So far I've seen crashes in creating SoundEffects items as well as
  removing them from the scene.
  
  Please find the example here: lp:~mzanetti/+junk/soundcrasher
  
  You should be able to run it on any vivid powered device by just opening
  the .pro file in QtCreator and hit the play button. The logs vary a lot
  between crashes. Sometimes I get some PulseAudio messages, sometimes it
  just crashes without any. Probably some raciness. Anyhow, this example
  app should be give the system a hard time and reveal most of the crashes
  eventually.
