I’m not getting audio when I edit x5 files on my laptop.

Not sure why there’s no audio , I am editing and reframing 360 footage - (pure video mode)from my Insta360 x5. using the desktop app, but there is no audio coming through during playback. When I export the mp4 files the audio still doesn’t come through but I can't hear it during editing/reframing. The audio is there when I play the files in the camera.
