Lanouncer and Big Talker

A while ago i installed the above so i could have sound and voice notification when certain things happened i.e. a tone when a door opened and a voice notification when it was time to pick my lad up from school .Lanouncer was set up on an old HTC phone and it all worked great … until now . All voice notifications do not play out loud , though the tones do and on IDE the logs show that voice notification is happening just no sound .

Any ideas
