I have made a debug patch for the demo version now so anyone who has the demo installed and cannot hear the sounds please run this patch:
www.antsairplanes.com/downloads/AntsWinjeelV101demodebug.zip
It shouldn't be a problem with the installation location as this works on other users systems and my own and FSX users are having sound problems.
I mention the output location as the Winjeel sounds go to the default output device only, so in case someone had it set differently. It seems this is not the problem as people have the sound problem with the default output device.
The new gauge file will tell me whether there is a problem initializing the direct sound buffer (which I think is the most likely cause) what that problem is. Without that information there is nothing I can do to work a solution.
Again, run the patch. Start the flight sim, load the Winjeel, Open Animation Manager - Preferences, click on SAVE and then either send a copy of My Documents/Ants Airplanes/Ants Winjeel/ either prefs.txt or P3D_prefs.txt to me or post the first 18 lines here.
Thank you.
