Hello,
I have a problem with the IONIC plugin NativeAudio.
I’m using IONIC with Capacitor with this configuration

Ionic:

   Ionic CLI                     : 5.4.16 (/usr/local/lib/node_modules/ionic)
   Ionic Framework               : @ionic/angular 5.0.7
   @angular-devkit/build-angular : 0.803.26
   @angular-devkit/schematics    : 8.3.26
   @angular/cli                  : 8.3.26
   @ionic/angular-toolkit        : 2.2.0

Capacitor:

   Capacitor CLI   : 2.0.1
   @capacitor/core : 2.0.1

Utility:

   cordova-res                          : not installed
   native-run (update available: 1.0.0) : 0.2.8

System:

   NodeJS : v13.11.0 (/usr/local/Cellar/node/13.11.0/bin/node)
   npm    : 6.13.7
   OS     : macOS Catalina

I install the Plugin as described in the DOC.

This is my sound service.

import {Injectable} from '@angular/core';
import {Platform} from '@ionic/angular';
import {NativeAudio} from '@ionic-native/native-audio/ngx';

const INCREASE = 'increase_audio';
const DECREASE = 'decrease_audio';


@Injectable({
  providedIn: 'root'
})
export class SoundService {
  
  private isSoundPlaying: boolean;
  private isAudioAvailable: boolean;
  
  constructor(
    private nativeAudio: NativeAudio,
    private platform: Platform
  ) {
    this.isSoundPlaying = false;
    this.isAudioAvailable = false;
    if (platform.is('hybrid')) {
      this.isAudioAvailable = true;
      this.nativeAudio.preloadSimple(INCREASE, 'sounds/increase.mp3').catch();
      this.nativeAudio.preloadSimple(DECREASE, 'sounds/decrease.mp3').catch();
    }
  }
  
  playIncrease() {
    this.playSound(INCREASE);
  }
  
  playDecrease() {
    this.playSound(DECREASE);
  }
  
  private playSound(soundId: string) {
    this.isSoundPlaying = true;
    if (!this.isSoundPlaying && this.isAudioAvailable) {
      this.nativeAudio.play(soundId).then(() => {
        this.isSoundPlaying = false;
      }, () => {
        this.isSoundPlaying = false;
      });
    }
  }
}

I inject it in a “controller” where I want to play the little sound.
I don’t inject anything in the app module, because is not reported in the documentation but I also try to put NativeAudio in the provider array but it still not working.

The error is : NullInjectorError: StaticInjectorError(AppModule)[NativeAudio]

As you can see in the image in attached.
