No audio from media files

When I add media file to a scene I can hear the sound on my default speaker and I can control the audio volume but there is no sound on my facebook live stream, I can only see the video.
When I add a capture device the audio and video is working fine and there is audio and video in my facebook livestream.

Thank you for reaching out to us, could you right click on the media file added as a source then take a screenshot of the source properties and send it to us?

And, send us a screenshot of your XSplit Broadcaster window aswell.
