Working with sounds/music on Android

I’m a Russian-speaking developer, and I’m temporarily working at GDevelop on Android, and I’m having a problem with sound and music playback.

I changed the format to WAV, I changed the hertz, worked with resources, event logic, and even asked the GPT chat But my sounds and music don’t play, not in viewing mode, not in the APK file, but the sounds from the GDevelop library work fine

I’ve already exhausted all options and don’t know how to solve the problem.
