Suspend AudioEngine before launching application

As described here http://forum.xbmc.org/showthread.php?tid=164522&pid=1417744#pid1417744

Patch is placed around all launchers so that it will suspend on all platforms instead of just linux.
If AudioEngine is not suspended this will cause problems for at least some linux users.
