What can interfere with the sound?

Question

Unity

AudioSource created by default did not twist anything, I call it as standard

public AudioSource AudioMusic;
public AudioClip MusicGeneral; 
if(!AudioMusic.isPlaying){
  AudioMusic.clip = MusicGeneral;
  AudioMusic.Play();
  }

I tested it on the computer, everything is fine, on the phone the noise is loud, as if you are twisting the plug to the speakers, everything is fine with the phone, everything is fine in other applications with sound. Some tracks downloaded to the phone, too, everything is fine.
What could it be? And it’s strange that I also made sounds and music in the previous application and everything was fine there, but here I don’t even know where to look ...
