No sound when playing video in ionic app on an iPhone device

Question

I have an ionic app that plays videos hosted on the internet. When testing the app on a web browser and in the iOS emulator the video plays with sound.

If I download the app onto my iPhone using X-Code the video plays but there is no sound!

Does anyone have an idea as to why the sound works on the emulator but not on the actual device? I have checked that youtube videos play ok with sound.

Answer 1

Ok, so I am clearly an idiot! The mute slider on my iPhone was turned on. Not sure though why this didn't mute youtube videos but did mute my app videos.

Answer 2

For those wondering why sound isn't working in the ionic view app for an iOS device, but it works in an iOS emulator like I was:

The ionic view app comes with a fixed set of cordova plugins. If your app needs a plugin which the ionic view app doesn't support thenyour app won't work in the ionic view app. The sound plugin I was using in my emulator wasn't supported in the ionic view app.

Edit: list of supported ionic view apps can be found here: http://docs.ionic.io/docs/view-usage
