title: Ionic Capacitor - Push Notification not making sound on iOS
body: <p>We're using <a href="https://capacitor.ionicframework.com/docs/guides/push-notifications-firebase/" rel="nofollow noreferrer">this guide</a> to create a pretty routine push notification system.</p>
  
  <p>We have everything working and push notifications are coming through. On Android, the push notifications make the default alert sound. On iOS however, no sound is made.</p>
  
  <p>How can we configure the push notification to use the default alert sound on iOS (we don't want to create/manage a custom alert sound).</p>
  
  <hr>
  
  <p>I've already configured the <code>presentationOptions</code> setting in the <code>capacitor.config.json</code> file.</p>
