I have created a basic indesign file consisting of 1 page that has 1 button and one audio file. I have set the button to play the audio file on click. I then exported in in5 as a webapp. I added the files to my server and tested on my iphone 6 Plus running IOS 10.2.1. The app downloads fine and I can see the button and audio file on the screen, though the button doesn't play the sound, I can tap the audio file and the playhead will start, but no sound is coming from the phone. Volume is all the way up. Weird thing is, I can hear it through headphones!
The same webapp downloaded onto my ipads and iphone 4s will play the audio as expected. Just not on my iphone 6 Plus.
If I upload the same file as an in5 web output, then open the url, the audio plays as expected on my iphone 6 Plus with or without headphones, so its not a speaker issue.
I have the latest in5 plugin and am using indesign cc 2017.
Any thoughts why I cant hear the audio files from my webApp in5 output only on my iphone 6 Plus on IOS 10.2.1 but can see the playhead playing and hear it only through the headphones?
