None of the examples of 1.09 api can work on my iphone7s, and i can play music with other app. Here’s a log of them. [LOG] System::create : Header version = 1.09.06. Current version = 1.09.06.

yes, it’s correct with my headphones. And i don’t get any sound from the main speaker of the phone with this example, but i can get sound from other apps. ---

Can I confirm, is the sound playing correctly through your headphones? But not through the main speaker of the phone? ---

I didn’t change the example settings, and the code is exactly the same with the official api example. [http://www.fmod.org/download/fmodstudio/api/iOS/fmodstudioapi10906ios-installer.dmg](http://www.fmod.org/download/fmodstudio/api/iOS/fmodstudioapi10906ios-installer.dmg) ---

It’s my fault, I have found the reason. My girlfriend had turned the sound button off !!! It’s a little button on one side of the iphone. ---
