iOS - Audio not working

Hello,

I've updated my unity project to the most recent, Unity 5.3.4, and I have discovered that my audio isn't working when I compile to iOS. The audio continues to work within the editor though.

I'm unsure why this would be. I'm also using Vuforia plugin, not sure if that has anything to don with it?

I created an empty project (excluding Vuforia) and the audio works fine on that.

And before you ask, no, my phone is not on mute, I've tried multiple apps with the audio working, and like I said, I created an empty unity project and compiled to iOS and that works fine too.

Any ideas? Thanks
