Ionic media iOS 11 - record audio issue when reusing same file / media object

Hi everyone,

I’ve got a problem with update to iOS 11.
I want to record an audio file. So what I do is :

• Create a new file using Ionic Native File
• Create a new media object based on the file using Ionic Native Media
• Start recording for 5 seconds
• Stop recording
• Start recording (using same media object) for 9 seconds
• Stop recording

Unfortunately, the second record length can’t be over the first record length. When I play the second one, it cuts at 5 seconds.

It worked pretty well on iOS 10 but starting in iOS 11 it just doesn’t accept a longer record.

Below is my code :

import { Media, MediaObject } from '@ionic-native/media';
// Things

let audioFileDirectory = this.file.tempDirectory;
        let audioFilename = 'recording.wav';
        this.audioFilepath = audioFileDirectory + audioFilename;
        this.file.createFile(audioFileDirectory, audioFilename, true).then(() => {
          this.audioFileMedia = this.media.create(audioFileDirectory.replace(/^file:\/\//, '') + audioFilename);
        });

this.audioFileMedia.startRecord();

this.audioFileMedia.stopRecord();

My environment is :

cli packages: (/usr/local/lib/node_modules)

    @ionic/cli-utils  : 1.19.0
    ionic (Ionic CLI) : 3.19.0

global packages:

    npm               : 5.4.2
    OS                : macOS High Sierra
    Xcode             : Xcode 9.2 Build version 9C40b
