title: SFML not playing sound when run in background
body: <p>I wrote an image processing program(c++) which is working fine on my cubietruck, when I run the program in console everything is working fine and the sound plays as I desire(I use SFML libary) , I need my program run whenever linux boot on my cubie so I modify the rc.local file as bellow ::</p>
  
  <pre><code>alias ls="ls --color"
  
  if [ -f /root/firstrun ]; then
      echo "first run setup"
      resize2fs /dev/nandb
      rm /root/firstrun
  else
      echo "not first run"
  fi
  modprobe sunxi_coded
  modprobe bcmdhd
  ifconfig eth0 0 up
  /root/shodet/shot
  exit 0
  </code></pre>
  
  <p>when the linux boot, my program starts and is working, but there is no sound , so I open a console, killall shot and then start it again and then I have sound ! 
  I have no idea whats wrong is it a SFML problem ? or something else 
  I appreciate your help 
  thanks in advance</p>
