Sound plays if device in silent mode

After device switching to silent mode (IOS) sound continues to play. How can I fix it or what a problem can this cause?

FMOD 2.00.07 and Unity 2019.4.4f1.

Hi Demonmal,

With FMOD 2.00.11 and Unity 2019.4.7 I am unable to reproduce this issue.

You may need to check your UnityAppController.mm and ensure that your AVAudioSession sharedInstance category is set to AVAudioSessionCategoryAmbient.
