Sound files not playing right when exporting to epub

Hi! 

I'm working on a picture book project that has audio files with speach on multiple pages. I'm trying to add the sound so that it plays when the user taps play, not on page load. When I review the pages on InDesign, the sound work as I want it to, but when I export the file as epub3, every soundfile repeats the first 2-5seconds of the speach and then cuts few seconds off at the end. I have tried to look for a solution and have followed multiple tutorials to make sure I'm adding the sound right, but I get the same issue every time. I've also tried multiple epub3 compatible readers to see if the issue was in the app I used but the sound issue is the same in them all.

I'm pretty new to InDesign and making epubs so I don't know if there is a setting I'm missing that would easily fix this, I just haven't been able to find anythings about a problem like this anywhere. I've been using v 15.1.2 of InDesign and my os is Windows 10 if that informations is helpful. Any suggestions for trying to fix this would be very welcome!
