Audio drops from videos when playing USB 3.0 iXpand drive on iPhone 7 and on iPad Air 2

I am having the same issue, but can’t seem to understand the solution. I am playing a .mp4 file but the audio cuts out after about 5 seconds, if I scroll ahead and try to play the video again as “resuming” the video, the middle audio comes fine and then goes away again.

I am travelling and have no computer, this was going to be my way of watching movies. Is it possible to fix this just using my iPad?
