iOS .ipa Build is wrongly setting the support for audio in the UIBackgroundModes key in your Info.plist, even without having this option being selected.
Apple has rejected our application :
" Guideline 2.5.4 - Performance - Software Requirements
Your app declares support for audio in the UIBackgroundModes key in your Info.plist but did not include features that require persistent audio.
The audio key is intended for use by apps that provide audible content to the user while in the background, such as music player or streaming audio apps. Please revise your app to provide audible content to the user while the app is in the background or remove the "audio" setting from the UIBackgroundModes key."
