Can't record audio

So i have a hard time trying to record audio :
My Code :

var my_media = new Media("toto.3gp",
()=>onSuccess(),
(err)=>onError(err),
(status)=>mediaStatus(status)
);
console.log(my_media); // Media

{id: "07053344-6274-09eb-62ca-d63f099f2a4b", src: "toto.3gp", _duration: -1, _position: -1}

my_media.startRecord();
console.log(my_media); // Media

{id: "07053344-6274-09eb-62ca-d63f099f2a4b", src: "toto.3gp", _duration: -1, _position: -1}

I made sure that the media object is correctly initialized and it is.

on Android console i got this:

07-10 19:59:20.019 31861-31917/com.phonegap.reacthotloadingtemplate E/MediaRecorder: start failed: -2147483648

Media Permissions are correctly set by the plugin (Automatically):

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

So what do you think the problem is ?
