I've gotten the scenes with the sound and motors to work just fine and have been able to synchronize them easily. My problem is with the two scenes that have sound only. I cant get them to run the sound file. I've tried swapping sound files with others that do run but this makes no difference. I'm using an RTC and this has worked well with the scenes that have DC motors. I've tried using both the RTC commands and also just a delay() command for the sound only scenes but still can't get them to run. I'll attach the sketch below. Would you please take a look and see if there's something I'm doing wrong here?
