I am trying to record a sound file using cordova-plugin-media, but I am always getting this error:
{message: "Failed to initialize AVAudioRecorder: (null)↵", code: 1}
I am first creating the file, like this
iOSCreateFile(fileName, callback) {
window.requestFileSystem(LocalFileSystem.TEMPORARY, 0, (fs) => {
fs.root.getFile(fileName, {
create: true,
exclusive: false
}, (fileEntry) => {
console.log("fileEntry is file?" + fileEntry.isFile.toString());
// here I am getting true, so the file is obviously created
callback(fileEntry.nativeURL);
}, (error) => {
console.log('error create file: ' + error);
});
}, (error) => {
console.log('error loading file system: ' + error);
});
},
The fileEntry.nativeURL I am sending back looks like this
file:///var/mobile/Containers/Data/Application/0EE019AA-EFBA-4FB9-97EC-1F16FFDDA36B/tmp/1496663387924.wav
then, when this calls back, I am doing the following
// that long file path string is passed here
let soundRecord = new Media(filePath, () => {
// success
// more code
}, (error) => {
console.log(error);
});
And once it tries to execute the new statement, it gives me the Failed to initialize AVAudioRecorder error...
What am I doing wrong please?
EDIT: I also tried not creating a file, but only passing a file name string to the new Media object, like "1240215251.wav", and it's supposed to create it for me, but I am still getting the same error.
UPDATE: I have tried to catch the error in the native code, but I don't understand it very well, when I am debugging I can only see where the error is generated, but nothing else, please check the below code, I have commented where needed

The issue could have probably happened because of the usage of cordova media plugin VERSION 3.0.0. This version had issues with recording "wav" files in iOS. An issue was already raised in media plugin's official issue tracker and its fixed in VERSION 3.0.1
So upgrading to the latest version of the plugin should resolve this issue. In this particular, the plugin wouldn't have got installed properly in the first try. Hopefully it should resolve the issue on proper upgrade. Cheers
