Please disregard my post about sound issues and the EZ app.  I am finding that our iphone works just fine with no lack of sound issues using the EZ App.  All functions with the app work.  I think the lack of sound using our iPad is a problem within the iPad's settings or preferences.  Thanks anyway!

ez app HO engine #6864 has lost its audio.  No bells or horns play through my Ipad.  The engine still functions with the ez app controls but no sound effects any more.     Sound effects worked fine  at first.   I have tried rebooting the ipad and reinstalling the EZ app from the app store and checking the 16 volt power source wired as DCC directly to the rails.  There is  now only one bluetooth  device,  my 6th generation ipad  connected to the train.  We did have the EZ app installed on our Iphone.  It also worked fine initially with sound  but no-longer.   To make sure there were not two conflicting  bluetooth devices  I uninstalled the EZ app from the cell phone.  The sound issue  still persists.
Any Suggestions?
Thanks Den
