Streaming Media Plugin playing no audio when silent switch off


I am using the Streaming Media Plugin to stream videos from a server.

I got the problem that the audio is not playing when the little silent switch on the left top side of the iPhone is off. But I want the audio to continue playing. Is there any solution to this?

Thanks in advance!

let options: StreamingVideoOptions = {
      successCallback: () => { ... },
      orientation: 'landscape'
this.streamingMedia.playVideo(video_path, options);
