SAB 9.3 audio not playing after build

Hello, i built a bible app with audio that is playing only on exportHTML, but when i build the android version, same audio in chapter is not playing when i tap the play icon.

But when i click on the synchronized audio file and exportHTML the audio plays as expected.

please how do i resolve this kind of issue. Im using Scripture App Builder 9.3. with Aeneas 1.7.2 not the python version.

operating system is MacOS Catalina

Thanks for you anticipated cooperation.
