Sorry if this has been asked before (I'm such a newbie -

) but I've created an intro for a video using the Intro Designer app (not impressed with that) and exported it to my photo's in iOS. When I play it back, I have sound. I then imported it to LumaFusion adding it to my project but once I play it there, there is no sound.
I've tried triple clicking to get the sound to the layer under the clip itself (little trick I found on here) and although that worked on another clip I created, it didn't work for me on this particular one.
Any thoughts?
Thanks so much!
