I just saw an error in the console and I noticed the TODO mark also: https://github.com/jsierles/react-native-audio/blob/master/ios/AudioRecorderManager.m#L246

error logged on the console is: error: The operation couldn’t be completed. (OSStatus error 1718449215.)

Hi there, I replicated this error seen by @hisankaran using a subset of the default configuration items. Similar setup except I am not using react-native-sound (yet). react: 16.8.3 react-native: 0.59.3 react-native-audio: 4.3.0

AudioRecorder.prepareRecordingAtPath(audioPath, {
       SampleRate: 44100.0,
       Channels: 2,
       AudioQuality: 'High',
       AudioEncoding: 'ima4',
      OutputFormat: 'mpeg_4',
       AudioSource: 0
    });

When I swapped it out for the AudioDemo config settings it worked as expected.

AudioRecorder.prepareRecordingAtPath(audioPath, {
      SampleRate: 22050,
      Channels: 1,
      AudioQuality: 'Low',
      AudioEncoding: 'aac',
      AudioEncodingBitRate: 32000
});

If I remove "ima4" and replace it with "aac" it does seem to work. Could "ima4" be the culprit?

Thanks, Joe
