[Android only] Audio file doesn't play

```
import {Media, MediaObject} from "@ionic-native/media/ngx";

constructor(
private media: Media,
) { }
```

```
const mp3file: MediaObject = this.media.create(url);
mp3file.play();
```

On iOs the code above is working properly, however on Android no sound is coming out and I have no error message.

Any idea ?

Start with the Android behavior of Media.create(url) and MediaObject.play() using the Ionic, Cordova, and Android versions reported in the issue, then compare it with the working iOS path. Reproduce the silent playback and inspect the Android-side result or error; done means the MP3 plays on Android or the failure is reported clearly.
