iPhone AVPlayer Streaming from Remote URL in PhoneGap

Programming for iPhone: iPhone AVPlayer Streaming from Remote URL in PhoneGap on newest questions tagged iphone – Stack Overflow

We are working on getting audio streaming from a remote URL in a iPhone application using a PhoneGap plugin written in Obj-C. For some reason, it is not playing the audio through the speakers, it only plays through headphones. We’ve tried using AVAudioPlayer with no luck. Do I need to set the audio output somewhere?
