Ionic-audio ios: webaudio not pause or native only plays last track


hey, i have the strange behaviour that in my ionic v2 project ionic-audio has some issues in ios. if i use webaudio i can’t pause any track. i start to playx. press on pause and it immediately starts again. if i use the jason example with several tracks with native audio it will only play the last track while safari debugging shows me that it handles the right track.
